SUMMARY:General Meeting - November 2019
DESCRIPTION:OUR LITTLE CORNER OF THE GALAXY – THE EARTHLIGHT EXPRESS\n  \nIn The Earthlight Express\, internationally published science artist Chris Butler brings his popular Our Little Corner of the Galaxy tours of the universe close to home – with an excursion across the wild and majestic wastelands of Earth’s moon.  Join Chris for a unique blend of science and imagination that will transform the distant moon you see in Earth’s sky into what it truly is: a world of its own. \n \nIn The Earthlight Express\, internationally published science artist Chris Butler brings his popular Our Little Corner of the Galaxy tours of the universe close to home – with an excursion across the wild and majestic wastelands of Earth’s moon at some time several centuries hence when such travel may be commonplace.  While earlier episodes of these tours required interstellar probes and spacecraft to visit far-flung destinations in the universe\, The Earthlight Express takes place close to home – which allows us to relax in comfort riding a lunar rail train of the future. \nWhile our method of travel is imaginary\, the places we will be visiting are all quite real.  Indeed\, we will pass through landscapes walked by three of the Apollo moon crews.  Placing ourselves into the scene permits us to appreciate the scope and scale of the places.  We will also be visiting parts of the moon Apollo never reached\, and seeing sights those astronauts never glimpsed\, such as the eerie majesty of the frigid lunar night.  In all\, our path will carry us across more than 2700 miles\, passing through wide valleys\, alongside towering mountains\, across deep crevasses\, and to the sheer lip of a gigantic crater that would hold a dozen large cities. \nChris conceived\, researched\, scripted\, designed\, modeled and edited all elements of the production over a course of four years\, making this the most ambition presentation he has undertaken yet in his 25 years of creating public science education shows. \n \nChris Butler is an internationally renowned artist\, public speaker\, and educational program producer whose work focuses on science\, nature\, and maritime subjects. His illustrations have appeared in thousands of publications worldwide\, from the Times of London to Scientific American. A graduate of California State University Fullerton’s school of Television and Film Production\, Chris has served as an art director and animator on both educational and entertainment programs. \nChris has served as an artist and animator for planetarium and exhibit programs for the Griffith Observatory in Los Angeles for 22 years\, and is a regular lecturer at education venues across the country. Chris’s unique art and presentation style reflects his diverse experience; he has been the director of a children’s science museum\, a tour guide on the original Queen Mary\, a technical illustrator\, a representative for a telescope manufacturer\, an amateur astronomer\, and a financial analyst on the space shuttle program for Rockwell International. \nChris was the 2006 recipient of the Western Astronomical Association’s G. Bruce Blair Medal for service to astronomy. Chris was also recognized in 2002 by having an asteroid named in his honor by the International Astronomical Union (minor planet 13543 Butler). In 2008\, Chris was elected as a Fellow of the Royal Astronomical Society (F.R.A.S.) in recognition of his service to international science education. \nAn avid amateur astronomer\, Chris brings direct experience with astronomy to his work. He has served as a vice-president and board member of the Orange County Astronomers (the largest organization of its kind in the world)\, and is a life member of the Los Angeles Astronomical Society. \nViews: 3

SUMMARY:General Meeting - December 2019
DESCRIPTION:Astro-cinematography from the Mount Laguna Observatory\n \nThe stars and galaxies that fill the night sky appear roughly today as they have throughout human history. However\, close inspection shows that these objects change\, sometimes dramatically\, over decades or months\, or occasionally over just minutes. The field of time-domain astronomy has arisen in recent years thanks to technological advances\, and we can now record these changes and reveal celestial mergers\, catastrophic explosions\, and the shadows of distant worlds. In this talk I will discuss our study of the time-variable universe from San Diego State University’s Mount Laguna Observatory including a new\, ultra-wide field imaging system that is beginning to survey the skies. \nRobert Quimby\n \nRobert Quimby is the Director of the Mount Laguna Observatory and an Associate Professor of Astronomy at San Diego State University. He earned his bachelor’s degree in Astrophysics from the University of California\, Berkeley in 1998 and then worked as a research assistant for the Supernova Cosmology Project before entering graduate school. Robert earned his masters and PhD in Astronomy from the University of Texas\, Austin in 2004 and 2006\, respectively. He went on to work as a postdoctoral scholar at Caltech and then at the Kavli Institute for the Physics and Mathematics of the Universe in Japan before joining the faculty at San Diego State University. Robert’s research interests include thermonuclear supernovae\, core-collapse supernovae\, the use of supernovae as cosmological probes\, detection of supernovae in the early universe\, gamma-ray bursts\, and other rare transient phenomena. For his research contributions\, Robert has received the Trumpler Award (Astronomical Society of the Pacific)\, the Hyer Award (American Physical Society)\, and\, a share of the 2015 Breakthrough Prize in Fundamental Physics. \nViews: 3

SUMMARY:General Meeting - January 2020
DESCRIPTION:Music of the Spheres: Gravitational Waves from Black Holes\n \nThe Nobel prize in 2016 was awarded for the detection of gravitational waves by the LIGO interferometer. So faint are these ripples that the only events powerful enough to produce detectable signals are the collisions of black holes and neutron stars\, some forty times the mass of the sun. I’ll explain how gravitational waves work\, how they are detected and explain some of the weird and interesting properties of black holes. \n \nSimeon Bird\, professor at UCR’s Department of Physics and Astronomy\, earned his Ph.D. from the University of Cambridge and did postdocs at the IAS in Princeton\, Carnegie Mellon and Johns Hopkins. His research interests are in cosmology and galaxy formation. His tool of choice is numerical simulations\, so he is interested in high performance computing\, as well as machine learning. His most notorious work connected the gravitational wave sources of LIGO with the very early universe. \nViews: 3

SUMMARY:General Meeting - February 2020
DESCRIPTION:From Apples to Orange Juice: Can We Infer a Galaxy’s Biography from Just One Photograph? \n \nDespite having data stretching back over 10 billion years and computer simulations that make realistic-looking galaxies starting from just gas and dark matter\, humans do not have a theory that predicts why a galaxy looks the way it does based on what it used to look like. We ask this from the biological theory of evolution\, but\, because astronomers cannot experiment on our subjects\, we face challenges biologists (and sociologists) do not. I will talk about the two main routes we are taking to overcome this handicap: (1) assuming our data nevertheless do look like that of biology or sociology and proceeding accordingly; (2) attempting to infer the past histories of individual objects through the single snapshots we actually have of them. The latter is the correct thing to do\, but it is unclear if it is possible\, which would leave astronomers in the unique position of having data…but nothing to do with it! This epistemological situation\, and the opportunity to explore questions like “Is galaxy evolution knowable?” is fascinating to me\, and I think it cannot but lead to important new insights about our place in the universe. \nLouis Abramson \n \nLouis Abramson is a Carnegie-Princeton Fellow at the Carnegie Observatories in Pasadena. He works to tease-out the growth histories of individual galaxies from information encoded in their colors. He hopes that such galaxy biographies will yield insights into what causes some galaxies to look like the Milky way while others do not. Outside of academia\, Louis is an elected official in the City of Los Angeles and chairs the Homelessness and Outreach Committees of the Central Hollywood Neighborhood Council. \nViews: 3

SUMMARY:General Meeting - June 2020
DESCRIPTION:This event has passed.\nTo provide feedback about the meeting\, click here.\n \nOur Dusty Universe\n\nThe two first images of ESO’s GigaGalaxy Zoom project combined to show a whole view of the Milky Way as could be seen with the unaided eye\, and a more central region observed with an amateur telescope. \n\n  \nMost of the heavy elements that make up the Earth and everything on it (including us) once resided in tiny grains of dust in interstellar space.  I will describe the fascinating lives of interstellar dust grains from their formation in fiery supernova explosions to their incorporation into planets like Earth.  Although dust is an important player in many processes happening in our Galaxy\, it is still very mysterious.  I will explain how we are working to understand the properties of interstellar dust both in our Galaxy and others using space telescopes like Spitzer\, Herschel and\, soon\, the James Webb Space Telescope.\n  \nKarin Sandstrom\n  \n\n  \nI received my Ph.D. in Astronomy & Astrophysics in 2009 from the University of California\, Berkeley. I then moved to Heidelberg\, Germany as a postdoctoral researcher in the Galaxies and Cosmology Department at the Max Planck Institute for Astronomy. In 2011\, I was awarded a Marie Curie fellowship from the European Union to continue my postdoctoral work at MPIA. I moved to Steward Observatory at the University of Arizona in 2013 to become the Bok Postdoctoral Fellow. In August 2015\, I started as an assistant professor at the University of California\, San Diego in the Center for Astrophysics and Space Sciences.\nViews: 3

SUMMARY:Online General Meeting - July 2020
DESCRIPTION:RSVP using the link on the box above.\nPlease install/update zoom client prior to the event.\n \nCosmic Dawn: The Birth of Galaxies in our Universe\n \nThe Milky Way is but one of an estimated two trillion galaxies in our observable Universe. Modern astronomical telescopes have revealed a rich ecosystem of galaxies\, but our Universe wasn’t always that way. In fact\, there was a time when galaxies did not exist. In this talk\, I will describe how astronomers are trying to unravel the mystery of how and when the first galaxies formed. \nAnson D’Aloisio\n \nI am an Assistant Professor in the Physics & Astronomy Department at UC Riverside. My research interests are in the fields of theoretical astrophysics and cosmology. I am particularly interested in the formation of structures in the Universe (e.g. galaxies and galaxy clusters)\, the epoch of reionization\, and gravitational lensing. I was born and raised in Middletown\, Connecticut. I did my undergraduate work at the University of California\, Riverside\, where I received my B.S. in Physics (minor in Math) in 2005. I went to graduate school at Yale University and received my Ph.D. in Physics in 2011. From there\, I took postdoctoral positions at the University of Texas at Austin\, and the University of Washington. \nViews: 3

DESCRIPTION:This event is free and open to public\, to attend please use the zoom registration link on the box above. \nSolar Eclipses: Math\, Science\, and Spectacle\nA composite image of the 2013 total solar eclipse at solar maximum. (Photos by Jay Pasachoff\, Allen Davis\, and Vojtech Rusin; computer compositing by Miloslav Druckmüller) \nAs a veteran of 72 solar eclipses —including 35 total solar eclipses\, 18 annular solar eclipses\, and 19 partial solar eclipses— astronomer Jay Pasachoff is uniquely positioned to share recent scientific work related to eclipses\, international coordination of observations\, and future plans. What role does mathematics play in predicting eclipses\, from the ancient saros observations to Halley’s 1715 map\, and up to today’s web-based zoom-and-click maps? How do theoretical predictions based on magnetic-field measurements\, emission spectra of high ionization lines\, and radio observations compare to the high res images available today? \nThe sky with the total eclipse corona and the umbra during the July 2\, 2019\, total solar eclipse photographed from the Cerro Tololo Inter-American Observatory\, Chile (David Sliski\, as part of the Williams College Expedition). \nThe beautiful streamers that become dramatically visible during an eclipse’s totality are shaped by the solar corona’s magnetic field. How do theoretical predictions based on magnetic-field measurements\, emission spectra of high ionization lines\, and radio observations compare to the high res images available today? \n \nI will discuss my expeditions to recent solar eclipses\, including total eclipses in the United States in 2017 and in Chile in 2019\, as well as the annular solar eclipse in India in 2019. I will also discuss the next solar eclipses\, including Chile and Argentina on December 14\, 2020\, and Mexico/United States/Canada on April 28\, 2024\, and the October 14\, 2023\, annular eclipse for which the partial-eclipse coverage of the Sun’s diameter from Orange County will be 78%. I will emphasize current topics of research of current solar eclipses\, and how they link with the Sun-Earth connection and our understanding of the coronas of trillions of other stars. \n  \nJay Pasachoff\n \nJay Pasachoff is Field Memorial Professor of Astronomy and Director of the Hopkins Observatory at Williams College\, Williamstown\, Massachusetts\, and a Visiting Scientist at Carnegie Observatories. (Prior to his Williams College appointment\, he was a postdoctoral fellow at Caltech and what was then called the Hale Observatories—Mt. Wilson and Palomar.) A veteran of 72 solar eclipses\, he is Chair of the International Astronomical Union’s Working Group on Solar Eclipses and a member of the American Astronomical Society’s Solar Eclipse Task Force. \n \nHis recent research includes studies of the dynamics of the solar corona studied from the ground at eclipses and from spacecraft\, and the temperature and structure of the corona over the solar-activity cycle from images and spectra. He also studies the atmosphere of Pluto through observation of stellar occultations and participated in the occultation study of Arrokoth that led to the diversion of NASA’s New Horizons spacecraft to image it on January 1\, 2019\, with the farthest-from-Earth photograph ever taken. His current eclipse research is supported by the Solar Terrestrial Program of the Atmospheric and Geospace Sciences Division of the U.S. National Science Foundation. His Pluto/Arrokoth research has been supported by NASA. \n \nPasachoff received the 2003 Education Prize of the American Astronomical Society\, the 2012 Janssen Prize of the Société Astronomique de France\, the 2015 Richtmyer Lecture Award from the American Association of Physics Teachers\, and the 2019 Klumpke-Roberts Award from the Astronomical Society of the Pacific. \nViews: 3

SUMMARY:Online General Meeting - September 2020
DESCRIPTION:This event is free and open to public\, to attend please use the zoom.us link on the box above. \nUncovering the Death Throes of Massive Stars Through Supernovae\n \nStars more massive than about 10 solar masses explode at the end of their life and die as supernovae. How massive stars look like when they explode? Astronomers try to answer this question through supernovae. It has been recently recognized that massive stars seem to have an unexpectedly active life just before they explode. In this talk\, I will introduce supernovae and what they tell us about the “death throes” of massive stars. \nTakashi Moriya\n \nI am an Assistant Professor at National Astronomical Observatory of Japan (NAOJ). I was born and grew up in Tokyo\, Japan. I received my PhD in Astronomy from the University of Tokyo in 2013. I worked at University of Bonn in Germany as a postdoctoral research fellow from 2013 to 2016 and moved to NAOJ in 2016. My research interest is mainly in theoretical aspects of supernovae and stellar evolution\, but I also work on observational astronomy using the Subaru telescope operated by NAOJ. \nViews: 3

A Story of How We Fixed It\n \nNASA’s Deep Space 1 (DS1) mission was designed to take risks so subsequent missions would not have to. Following its successful 1998-1999 prime mission to test new technologies\, DS1 embarked on an ambitious two-year extended mission dedicated to comet exploration. However\, that journey was soon interrupted as the probe suffered a hardware failure widely considered to be catastrophic. \nUnder Marc Rayman’s leadership\, the JPL operations team then undertook one of the most remarkable deep-space rescue missions ever attempted. After seven months of intensive and stressful work\, they managed to restore the spacecraft to an operational capability from well over 150 million miles away. DS1 then resumed its pursuit of the comet. The team encountered and overcame more daunting challenges in the subsequent 15 months\, and in 2001 they succeeded in acquiring NASA’s first close-up images of a comet nucleus and other unique data. \n \nThis extraordinary and exciting success story is not well known\, even among the astronomy and space communities. Dr. Rayman described it in a highly entertaining and inspiring public presentation last year. He will introduce the video\, we will all watch it\, and then he will answer questions. The video can be found here. \nMarc Rayman\n \nMarc Rayman is not only a top rocket scientist at NASA’s Jet Propulsion Laboratory but also a magnificent communicator. He is currently JPL’s chief engineer for mission operations and science. \nHe grew up in Toledo\, Ohio\, and earned a B.A. in physics from Princeton University. His undergraduate work focused on astrophysics and cosmology. He received an M.S. in physics from the University of Colorado in Boulder\, where he conducted investigations in nuclear physics. He then performed research at the Joint Institute for Laboratory Astrophysics (JILA) on experimental tests of special relativity and atomic and laser physics\, and received his Ph.D. there. He continued at JILA as a postdoctoral researcher. Throughout his time at JILA\, he worked with Dr. John Hall\, who subsequently won a Nobel Prize in Physics. \nDr. Rayman combined his scientific training with his lifelong study and passion for astronomy and the exploration of space by joining JPL in 1986. His work there has spanned a broad range\, including optical interferometry missions to detect planets around other stars\, design of a mission to return samples from Mars\, a laser altimeter for Mars\, the Spitzer infrared space telescope\, the development of systems to use lasers instead of radios to communicate with interplanetary spacecraft\, and more. \n \nIn 1994\, he helped initiate a new NASA program to characterize highly sophisticated and risky technologies for future space science missions by flying them on dedicated test flights. The first mission of this New Millennium program\, Deep Space 1\, was launched in 1998\, and he worked on it from its inception in 1995 to its conclusion in 2001. During the course of the project\, Dr. Rayman served as chief mission engineer\, mission director\, and project manager. The new technologies that were tested on DS1 (including such exotic systems as ion propulsion and artificial intelligence) were designed to reduce the cost and risk and to improve the performance of subsequent interplanetary missions. The primary mission was extremely successful and led to a very productive and exciting extension\, culminating in a spectacular encounter with Comet Borrelly that yielded NASA’s first close-up pictures of the nucleus of a comet. The spacecraft remains in orbit around the Sun. \nHe was chief engineer\, mission director\, and project manager on a mission that built on DS1 to explore the two largest uncharted worlds in the inner solar system. Launched in 2007\, Dawn orbited two giants of the main asteroid belt\, protoplanet Vesta and dwarf planet Ceres\, in an ambitious mission to reveal insights into the dawn of the solar system. After a spectacularly successful investigation of Vesta in 2011-2012\, it arrived at Ceres in 2015\, where it will remain forever. It is the only spacecraft ever to orbit two extraterrestrial destinations. The spacecraft outlasted its expected lifetime\, and the mission concluded successfully in 2018. \n \nDr. Rayman is the recipient of numerous honors. His many accolades from NASA include a remarkable three Exceptional Achievement Medals and four Outstanding Leadership Medals\, which are among NASA’s most selective awards. He was named a JPL Fellow\, the highest technical position there\, “for extraordinary technical contributions made over an extended period.” He is the only person to have received both the Exceptional Technical Excellence Award and the Exceptional Leadership Award\, two of JPL’s most prestigious honors. Asteroid Rayman was named in recognition of his contributions to space exploration. On behalf of the Dawn team\, in 2016 he accepted the Robert J. Collier Trophy\, the greatest award in the US for space or aviation. (The trophy resides at the Smithsonian National Air & Space Museum in Washington.) Among his other honors was receiving the Astronautics Engineer of the Year Award from the National Space Club and Foundation. \n \nMarc is also very active in education and public outreach. He is a highly regarded and very popular speaker\, relating the thrill of science and the excitement of discovery\, and he has appeared frequently on television and been quoted often in other news media on subjects as wide-ranging as DS1 and Dawn\, a fire onboard the Mir space station\, the discovery of the top quark\, and the profundity of humankind’s exploration of the cosmos. He collaborates with the creator of the popular syndicated comic strip Brewster Rockit: Space Guy! for special editions on science topics. His DS1 blog had an enormous following and gained critical acclaim as it provided an exceptionally entertaining and informative view into the flight of DS1\, and his Dawn blog continued in the same delightful style. Marc is technical advisor and a popular writer for NASA’s educational website the Space Place (where his digital alter ego\, Dr. Marc\, resides). Marc received a special award from JPL for his creative and engaging work to inform and inspire the public. \nIn addition to more than 75 scholarly publications in physics\, space science\, and space engineering\, he has published many articles on Apollo\, Skylab\, the space shuttle\, piloted and robotic missions of the former USSR\, interplanetary missions\, and a variety of topics in astrophysics\, cosmology\, and space exploration for reference books\, encyclopedias\, magazines\, and newspapers. \n \nOne of Marc’s favorite hobbies is learning about the space activities of all space-faring nations.

SUMMARY:Online General Meeting - October 2020
DESCRIPTION:This is an online event\, to attend please register with zoom using the link on the box above. \nDownload: Club Announcements \nThis meeting’s speaker changed at the last minutes and the information reflected here has not been updated. \nDark Matter and the Dance of Dwarf Galaxies\n \nMajor galaxies\, such as our cosmic home the Milky Way\, the nearby Andromeda galaxy\, or Centaurus A\, are surrounded by swarms of smaller dwarf satellite galaxies. Over the past 15 years\, our knowledge of these satellite galaxies has exploded. The number of known Milky Way satellites has quadrupled\, and highly precise measurements of their motions have provided unprecedented insights into their complex orbital dance. In my research\, I investigate the distribution and motion of satellite galaxies to test our ideas of how the cosmos in general\, and galaxies in particular\, have formed and evolved. Our current leading model of cosmology was largely developed on cosmic scales\, and implies that most of the mass in the Universe is dominated by unknown stuff: Dark Matter. Based on this cosmological model\, computer simulations can nowadays follow the emergence and evolution of structure in model universes. These simulations predict the distribution and properties of galaxies down to the smallest scales (astronomically speaking). They predict a highly chaotic tangle of satellite galaxies. In contrast\, my research finds that the observed situation resembles an ordered choreography: the satellite galaxies around the Milky Way\, Andromeda\, and Centaurus A are aligned along planes. Many satellites also move along these structures in a common direction. This finding poses a serious challenge to our model of cosmology – and might point at a fundamental misinterpretation of cosmic proportions. \nMarcel S. Pawlowski\n \nMy research is situated at the intersection of observations and cosmological simulations. I am most interested in testing our cosmological knowledge and our understanding of the properties and dynamics of dwarf galaxies with observations of nearby systems of satellite galaxies. After receiving my PhD from the University of Bonn in 2013\, I moved to the United States for a postdoc position at Case Western Reserve University in Cleveland\, Ohio. In 2016\, I was awarded a NASA Hubble Fellowship to work at the University of California Irvine. At the end of 2018 I moved back to Germany to my current position as Schwarzschild Fellow at the Leibniz-Institute for Astrophysics in Potsdam. \nViews: 3

SUMMARY:Online General Meeting - November 2020
DESCRIPTION:This is an online event\, to attend please register with zoom using the link on the box above. \nNASA’s New Horizons Mission to Pluto and Beyond\n \nSince its launch in 2006\, the New Horizons spacecraft has been speeding out of the solar system\, transforming our understanding of planetary science along the way. In 2015\, it provided the first close-up views of the Pluto system and revealed an astonishingly active world\, replete with active glaciers\, dynamic atmosphere\, and possible signs of cryovolcanism. Four years (and about five astronomical units) later\, New Horizons went on to perform the first flyby of a small Kuiper Belt Object: (486958) Arrokoth (formerly 2014 MU69). This 30-km wide\, icy world is a relic of planet formation\, with its own odd geology and formation story. In this talk\, I’ll recap New Horizons amazing journey—and my parallel journey here on Earth\, going from a graduate student\, competing against the New Horizons team\, to a researcher embedded within the team and shaping its future. I’ll close with some perspective about future exploration of the outer solar system. \nJames Tuttle Keane\n \nDr. James Tuttle Keane hails from Cedar Rapids\, Iowa. He received a bachelor’s degrees in Astronomy and Geology from the University of Maryland\, College Park\, and a doctorate in planetary science from the University of Arizona. After a postdoctoral position at the California Institute of Technology\, he started at JPL in 2020. Dr. Keane is a planetary scientist\, studying the interactions between orbital dynamics\, rotational dynamics\, and geologic processes on rocky and icy worlds across the solar system. He uses a combination of theoretical methods\, coupled with the analysis of spacecraft-derived datasets to investigate the dynamics\, structure\, origin\, and evolution of solar system bodies. He has extensive experience with NASA missions\, including GRAIL\, New Horizons\, and the proposed Io Volcano Observer. \nViews: 3

SUMMARY:Online General Meeting - December 2020
DESCRIPTION:This is an online event\, to attend please register with zoom using the link on the box above. \nState of the Universe Report\n \nThis lecture will discuss the current understanding and the latest discoveries regarding cosmology—the science of the universe as a whole—and galaxies and planets. There is overwhelming evidence that most of the density of the universe is invisible dark matter and dark energy\, with atomic matter making up only about five percent of cosmic density. UC Santa Cruz cosmologists helped to create the standard modern cosmological theory—but the latest high-precision measurements have revealed potential discrepancies that may require new physics. Galaxies were long thought to start as disks of gas and stars\, but observations by Hubble Space Telescope show that most galaxies instead start pickle-shaped. More massive galaxies have massive black holes at their centers\, and matter falling onto these black holes causes outflows of energy that can strongly affect their host galaxies. Information about planetary systems is growing rapidly with new observations\, and our own solar system seems increasingly to be unusual. \nJoel R. Primack\n \nJoel R. Primack specializes in the formation and evolution of galaxies and the nature of the dark matter that makes up most of the matter in the universe. After helping to create what is now called the “Standard Model” of particle physics\, Primack began working in cosmology in the late 1970s\, and he became a leader in the new field of particle astrophysics. His 1982 paper with Heinz Pagels was the first to propose that a natural candidate for the dark matter is the lightest supersymmetric particle. He is one of the principal originators and developers of the theory of Cold Dark Matter\, which has become the basis for the standard modern picture of structure formation in the universe. With support from the National Science Foundation\, NASA\, and the Department of Energy\, he has been using supercomputers to simulate and visualize the evolution of the universe and the formation of galaxies under various assumptions. \nHere’s the link to a recording of my 10 November 2020 UCSC Emeriti Research Lecture “State of the Universe Report: Cosmos\, Galaxies\, Planets” on YouTube:\nhttps://www.youtube.com/watch?v=BAuiSC0iUXE\n\nHere are some of my recent research results that may be of wider interest:\n\n— Local measurements of the the Hubble parameter give H_0 = 73 ± 1 km/s/Mpc\, while measurements of the Cosmic Microwave Background extrapolated to the present with the standard ΛCDM cosmology give H_0 = 67 ± 0.5 km/s/Mpc.  This “Hubble tension” could be resolved if there was a brief period when dark energy contributed about 10% to the cosmic density about 35\,000 years after the Big Bang.  I initiated the first N-body simulations with this Early Dark Energy (EDE) cosmology.  Our paper on this https://arxiv.org/pdf/2006.14910.pdf was led by Anatoly Klypin.  We found that EDE predicts 50% more rich clusters of galaxies at redshift z=1 than standard ΛCDM\, and many more galaxies at higher redshifts.  These predictions will be tested by new astronomical surveys now underway. We are resubmitting the paper to MNRAS in response to a favorable referee report\, so it will be published soon.  We are setting up to run 500 Mpc/h paired simulations with Bolshoi resolution of standard ΛCDM and EDE; the use of the same random number seed will ensure that all the large-scale structures will correspond in these simulations.  We plan to do abundance matching with both simulations\, to fill all the halos with UniverseMachine and Santa Cruz SAM galaxies\, and to compare with observations.\n\n— I initiated a paper that shows that Earth may be a “Goldilocks” planet in a new way\, with enough radioactive heat generation to power plate tectonics and not too much to kill the geodynamo generating the Earth’s magnetic field.  Tectonics and a magnetic field may both be necessary for the evolution of complex life.  Earth’s radioactive heat is generated by the two longest-lived radioactive elements thorium and uranium\, which are produced in extremely rare events such as neutron-star mergers — as a result\, the amount of Th and U varies a lot between different planetary systems.  Our paper\, led by my UCSC colleague Francis Nimmo\, was published November 10\n https://ui.adsabs.harvard.edu/abs/2020ApJ…903L..37N\nThe UCSC press release is at https://news.ucsc.edu/2020/11/planet-dynamos.html \,\nwith some popular articles at\nhttps://astrobiology.nasa.gov/news/how-radioactivite-elements-may-make-planets-suitable-or-hostile-to-life/\nhttps://www.scientificamerican.com/article/stellar-smashups-may-fuel-planetary-habitability-study-suggests/\nhttps://cosmoquest.org/x/2020/11/radioactive-elements-may-be-crucial-to-rocky-planets-habitability/\nhttps://www.centauri-dreams.org/2020/11/13/radioactive-elements-and-planetary-habitability/\nhttps://astrobites.org/2020/11/17/radiogenic-heat-hurts-dynamos/\nhttps://www.universetoday.com/148796/what-role-do-radioactive-elements-play-in-a-planets-habitability/\n\n— I’ve continued to make novel uses of machine learning to compare simulations with observations and to analyze observations.  My group’s latest papers on this focused on giant clumps found in HST images of most redshift z > 1 star-forming galaxies.  In https://ui.adsabs.harvard.edu/abs/2020MNRAS.499..814H we trained a CNN to measure the masses of giant clumps; we made public our analysis of the entire CANDELS galaxy dataset\, and we used a complete set from GOODS-N and S with 7 wavebands to measure clump properties as functions of galaxy properties including sSFR\, radius\, and stellar mass.  In https://ui.adsabs.harvard.edu/abs/2020arXiv201106616G we trained a CNN to measure the lifetimes of the clumps in the CANDELS data; this paper was just accepted for publication.  Our earlier paper that made extensive use of machine learning to compare HST observations with theory was profiled in https://news.ucsc.edu/2018/04/deep-learning-galaxies.html \n\n\nViews: 3

DESCRIPTION:This is an online event\, to attend please register with zoom using the link on the box above. \nGearing Up to Explore an Icy Moon: the Europa Clipper Mission\n \nWhat is just a quarter the diameter of the Earth but may have twice as much water as of all the Earth’s oceans combined under an icy shell? Meet Europa – a beautiful ice-ocean moon of Jupiter that may have all of the ingredients necessary for life. \nFlight Systems Engineer Tracy Drain will give you an inside peek into the mission that is in development right now\, preparing to go explore this fascinating place. The Europa Clipper spacecraft will carry a suite of science instruments on a journey from the Earth out to the Jupiter system. Once there\, it will execute a series of close flybys of Europa\, braving the intense radiation field that surrounds Jupiter\, to gather the data that will help scientists answer some long-standing questions about this world. \nTracy Drain\n \nTracy Drain is a Flight Systems Engineer working at NASA’s Jet Propulsion Laboratory. In her 20 years at JPL\, she has participated in the development and operation of the Mars Reconnaissance Orbiter (a science and relay orbiter at Mars)\, the Kepler mission (searching for Exoplanets)\, the Juno mission (a science orbiter at Jupiter)\, and the Psyche mission (an asteroid mission slated to launch in 2022). She is now the lead Flight Systems Engineer for the Europa Clipper mission\, currently planned to launch in 2024. A life-long learner\, Tracy loves to encouraging people of all ages nurture their curiosity and explore the wonders that surround us every day. \nhttps://europa.nasa.gov/mission/about/ \nhttps://europa.nasa.gov/resources/148/europa-water-world-infographic/ \n  \nViews: 3

SUMMARY:Online General Meeting - April 2021
DESCRIPTION:This is a free online event\, to attend please register with zoom using the “View Event Website” link on the box above. \nWhat will astronomy be like in 2121?\n  \n \nAstronomy texts of 2121 will be filled with answers to questions we haven’t thought to ask in 2021. I say this based on how unpredictably our cosmic view has changed in the past century. How did Canadian astronomer John Stanley Plaskett see the Universe in 1921 when his namesake telescope saw its first light? How might he have answered the question “What will astronomy be like in 2021?” In 1921\, the Milky Way was the entire Universe\, and almost all astronomers were sure we were near its centre. In 1921\, the most sensitive thing at the focus of a telescope was photographic emulsion on a piece of glass\, and the only light recorded was what we see by eye\, a sliver of the electromagnetic spectrum. The first radio telescope was more one decade away. People dreamt of space travel but no one included a telescope in those dreams. So space telescopes weren’t yet even a fantasy. In 1921 (and for the next five decades)\, the recipe of the Universe was simple. Everything was made of atoms\, made of particles of ordinary matter. There was one type of matter\, so nobody said “ordinary matter”\, just “matter”. No one in 1921 had predicted\, or even imagined\, dark matter and dark energy. No one in 1921 predicted the expansion of the Universe. Well\, Einstein did\, or his Theory of General Relativity had. But Einstein thought it was a flaw in his theory. Einstein predicted black holes in 1916 but they weren’t named that until 1967 and the first wasn’t found until 1971. He predicted gravitational waves in 1916; it was a century before that prediction was confirmed. Fast forward to 2021\, as I try to forecast the state of astronomy in 2121. Like Plaskett\, there are advances I can confidently predict. We’ll know the nature of dark matter\, maybe within a decade. Gravitational wave detectors will see things so distant we couldn’t study them in any other way. We’ll have mapped stars across our Galaxy. Our sample of planets around those stars will grow from a few thousand today to maybe a few million in 2121. And we’ll have evidence of aliens – maybe only microbes\, but alien microbes nonetheless. The biggest breakthroughs will be the ones no one sees coming. Whenever we look at the Universe with new eyes (telescopes and instruments)\, new insights (analyses powered by new computers and young minds) or new perspectives\, we are always caught off guard. I hope to catch you a bit off guard with my look back across a century of astronomical history and with my speculative look forward across the next century of discovery \n \nJaymie Matthews calls himself an astrophysical “gossip columnist” who unveils the hidden lifestyles of stars by eavesdropping on “the music of the spheres.” His version of interstellar Spotify is Canada’s first space telescope\, MOST (Microvariability & Oscillations of STars)\, which detects vibrations in the light of ringing stars too subtle to be seen by the largest telescopes on Earth. MOST also makes Professor Matthews an “astro-paparazzo” by helping him spy on planets around other stars that might be homes for alien celebrities. Celebrities? Maybe not Wookies\, but finding microbes on another world would qualify those microbes as newsmakers of the century. Matthews is a Professor of Astrophysics in University of British Columbia’s Department of Physics & Astronomy. Prof. Matthews is an expert in the fields of stellar seismology (literally using the surface vibrations of vibrating stars to probe their hidden interiors and histories) and exoplanetary science. He’s a member of the Executive Council for NASA’s Kepler satellite mission hunting for Earth-sized exoplanets in the Habitable Zones of their stars. He serves on the Science Team for BRITE Constellation (BRIght Target Explorer) – a Canadian–Austrian–Polish satellite mission monitoring the brightest stars in the night sky. He’s an Associate Editor of the astronomy journal Frontiers\, and an author on more than 200 refereed scientific papers. In 2006\, Prof. Matthews was appointed an Officer of the Order of Canada\, and in 2012\, he received a Queen Elizabeth II Diamond Jubilee Medal. Astronomy education and public outreach are important facets of Matthews’ life and career. He’s UBC’s astronomy undergraduate advisor. He served on the Board of Directors of Vancouver’s H.R. MacMillan Space Centre for almost 20 years\, and on the Board of Youth Science Canada. In 2015\, he received the Canada-Wide Science Fair Alumni Award. He was awarded a 1999 Killam Prize for teaching excellence in the UBC Faculty of Science\, and the 2002 Teaching Prize of the Canadian Association of Physicists. In 2016\, Dr. Matthews was awarded the Canadian Astronomy Society’s Qilak Award for his efforts in astronomy education and public outreach. Qilak is the Inuit word for the “canopy of the heavens” or the sky overhead. Matthews is a co-founder of and regular instructor in UBC’s Science 101 course for residents of Vancouver’s Downtown East Side\, and a mentor for Canada’s Loran Scholar programme. He was a storyteller at the Kootenay Storytelling Festival in Nelson\, BC in 2013. Last year\, Dr. Matthews provided astronomical context on stage for a sold-out concert by the UBC Symphony Orchestra of Holst’s The Planets. \nViews: 3
