SUMMARY:Online General Meeting - October 2021
DESCRIPTION:This is a free and open to the public online event\, to attend please register with zoom by clicking here.\n \nThe “What’s Up?” presentation at this meeting will feature an android app called “Mobile Observatory” those interested are advised to install it on their cell phone before the meeting by clicking here and then download the extended catalogue within the app.\n \nStars are not Spherical Cows\n  \n \n  \nStars are the sources of all the light we see in the universe. Whether we are investigating our own celestial neighborhood\nor the most distant corners of the universe\, we use stars as our beacons. The universe is mostly made of dark energy\, and galaxies and clusters mostly of dark matter. But it is stars like our sun that trace them all. Stars are not eternal balls of gas churning out energy from their nuclear furnaces. They are born\, they live\, and they die. The birth of stars is particularly important as it can be traced back to the birth and evolution of galaxies across cosmic times. I will review progress over the past decade in understanding how stars form out of the gas clouds that pervade galaxies\, and how this has helped with furthering our understanding of the universe. Space missions\, as well as advanced ground-based telescopes\, have played key roles in advancing our knowledge. With many challenges still ahead of us\, the way forward will require innovative thinking for the future missions and facilities that will enable humanity one day to say\, “We know where we came from.” \n \nDaniela Calzetti is an astronomer recognized for her investigations on the interstellar dust and star formation in external galaxies. Calzetti  obtained her PhD at the University of Rome in 1992. In 1990\, she became first an ESA Fellow and then a postdoc at the Space Telescope Science Institute (Baltimore\, MD\, U.S.A.). Here\, she was hired as an astronomer in 1995\, and worked on characterizing and supporting instrumentation on the Hubble Space Telescope for NASA. In 2007\, she moved to a faculty position at the University of Massachusetts\, Amherst\, where she is serving as the Head of the Astronomy Department since 2018. In 2013\, she was named the Blaauw Professor at the Kapteyn Observatory (University of Gröningen\, The Netherlands)\, and in 2016 she was awarded the Tage Erlander Guest Professorship by the Swedish Research Council\, which she spent at the University of Stockholm (Sweden). Calzetti was elected to the National Academy of Sciences in 2020. \n  \nViews: 3

SUMMARY:Online General Meeting - September 2021
DESCRIPTION:This is a free online event\, to attend please register with zoom using the “View Event Website” link on the box above. \nRadio astronomy in South Africa:\n  \nBackground\, recent discoveries\, and role\n\n  \nin the development of the continent\n  \n \nOur understanding of the universe is being comprehensively revisited thanks to a new generation of telescopes that are true big data machines. A region of the world where astronomy is growing faster than anywhere else\, is probably Africa\, a continent not traditionally associated with groundbreaking astronomical research. In South Africa\, the radio astronomy community\, in particular\, has grown from merely present to broad and inclusive\, thanks to the country’s commitment to the Square Kilometer Array (SKA) radio telescope project\, and the home-grown human capacity development programme that accompanies it. \n \nThis presentation will set the context of this growth\, review a few recent discoveries made with the MeerKAT radio-telescope\, a 64-dish interferometer precursor to the SKA\, and discuss the many developments\, both scientific and social\, that have been triggered by the South African SKA project. Indeed\, the engagement into a scientific programme of this scale in Africa is not without broader impacts\, social\, economic and educational. \n \nIt will conclude with a view of the future\, and the scientific ambitions of a continent and a community now able to use Africa’s big skies to pursue big dreams. \nDr. Carolina Ödman\n \nDr. Ödman is Associate Professor at the University of the Western Cape\, South Africa. Trained in physics at EPFL in Switzerland\, she holds a PhD in cosmology from Cambridge University\, UK. After a Marie Curie postdoctoral research fellowship in Italy\, she grew an interest in education\, becoming the first international project manager of Universe Awareness\, an early childhood development program that uses the inspirational aspects of astronomy to stimulate children’s development in underprivileged environments. She led Universe Awareness for 5 years\, taking it from an idea to a global network of volunteers running projects in more than 40 countries. \n \nShe joined the South African Astronomical Observatory as an SKA Research Fellow working at the interface between astronomy and technology\, which she continues\, as founding member of the “.astronomy” (dot-astronomy) conference and hackathon series. She was Director of Academic Development for the Next Einstein Initiative before joining thumbzup\, a financial technology start-up as Chief Scientist. At thumbzup she set up a data science and analytics pipeline. In 2018\, she joined the Inter-University Institute for Data Intensive Astronomy as Associate Director\, Development and Outreach. There\, she leads a number of initiatives\, including big data skills development\, and continues to do multidisciplinary research on how big data and astronomy can contribute to development of communities and society at large. Her work has earned her numerous awards\, including Inspiring Fifty South Africa (2020)\, an International Astronomical Union Special Award for Astronomy Outreach\, Development and Education (2018)\, Mail & Guardian Top 200 Young South Africans (2014)\, Bilan Magazine 300 most influential of Switzerland – category under 40s (2013)\, an American Association for the Advancement of Science Prize for Online Resources in Education (2010). \nhttps://carolune.org\nhttps://astro.uwc.ac.za\nhttps://www.idia.ac.za \nViews: 3

SUMMARY:Online General Meeting - August 2021
DESCRIPTION:This is a free online event\, to attend please register with zoom using the “View Event Website” link on the box above. \nInto the Void: Probing the Space between\n  \nPlanets\, Stars\, and Galaxies\n  \n \nIt is hard for us to grasp how vast and how empty space is\, but it is also true that the vast majority of matter in the universe is distributed at barely-detectable densities through the voids between planets\, stars\, and galaxies. The propagation of radio pulses through the tenuous interstellar and intergalactic media offers a unique probe of this gas. Pulses from radio pulsars – rapidly spinning neutron stars – have been used to map the ionized interstellar medium of the Milky Way. \nInto the Void with Voyager\, Pulsars\, and Fast Radio Bursts\n \nThe recent discovery of fast radio bursts has allowed us to start probing the intergalactic medium even as we try to understand what powers these enigmatic radio pulses from distant galaxies. Closer to home\, data from the Voyager spacecraft has revealed a new way to monitor the boundary between the solar wind and interstellar space. We will take a quick tour of these diverse phenomena\, and what we have learned so far. \n  \n \nShami Chatterjee is a Principal Research Scientist at the Cornell Center for Astrophysics and Planetary Science and the Carl Sagan Institute\, which seems like coming full circle\, since he grew up watching Carl Sagan’s Cosmos and dreaming about the stars. Dr. Chatterjee studies neutron stars\, works on the forefront of efforts to use them to build a low-frequency gravitational wave detector\, and has been in hot pursuit of fast radio bursts\, mysterious flashes of radio waves that are coming from billions of light years away. \nDr. Chatterjee has a PhD in astronomy from Cornell University\, and he was a Jansky Postdoctoral Fellow at the National Radio Astronomy Observatory in Socorro\, New Mexico and the Harvard-Smithsonian Center for Astrophysics in Cambridge\, Massachusetts. After a stint as a University Fellow at the University of Sydney in Australia and as an astronomer at the Australia Telescope National Facility\, he has been at Cornell University since 2009. \n \nDr. Chatterjee’s work has appeared on the cover of Nature\, in the New York Times and Washington Post\, and has even been picked up by his hometown newspaper in Kolkata\, India. He enjoys a quiet life in upstate New York with his lovely wife and wonderful children\, and laments the fact that his to-read pile grows faster than he can possibly keep up with. \n  \n  \nViews: 3

SUMMARY:Online General Meeting - June 2021
DESCRIPTION:This is a free online event\, to attend please register with zoom using the “View Event Website” link on the box above. \nHearing the Stars:\n  \nNew Insights into Stellar Interiors\n  \nSpace-based observations from the Kepler satellite have provided a remarkable new tool for studying stars. Simply by measuring how bright a star is over many years\, we can now directly measure its mass\, radius\, rate of rotation\, and sometimes\, the magnetic field it possesses. This has now been done for tens of thousands of stars across the Milky Way\, also allowing us to identify those few stars that are in short-lived phases of their evolution. It’s a great story of how theory and observation\, together\, can make a remarkable impact on our understanding of the universe. \n  \nLars Bildsten is the Director of the Kavli Institute for Theoretical Physics (KITP) and the Gluck Professor of Theoretical Physics at the University of California\, Santa Barbara. He received his PhD in theoretical physics from Cornell University in 1991\, where he held a Fannie and John Hertz Graduate Fellowship. Dr. Bildsten is a theoretical astrophysicist recognized for his work on the properties and behaviors of stars\, both when they are burning their thermonuclear fuel for billions of years and when they explode as supernovae or emit gravitational waves. He was at Caltech for three years as the Lee A. DuBridge Research Fellow in Theoretical Astrophysics and was an assistant and associate professor in both the Physics and Astronomy departments at University of California\, Berkeley. Moving to Santa Barbara in 1999 as a Permanent Member at the KITP\, he held the Rosing\, Raab Chair in Theoretical Astrophysics prior to becoming Director in 2012. Among his awards are the Alfred P. Sloan Foundation Fellowship\, the Cottrell Scholar of the Research Corporation\, the Helen B. Warner Prize from the American Astronomical Society and the Dannie Heineman Prize for Astrophysics. He is a Fellow of the American Association for the Advancement of Science\, the American Physical Society\, the American Astronomical Society and was elected to the National Academy of Sciences in 2018. He is presently Chair of the Board of Directors of both the Research Corporation for Science Advancement and the Las Cumbres Observatory. \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

SUMMARY:Online General Meeting - March 2021
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 - January 2021
DESCRIPTION:This is an online event\, to attend please register with zoom using the link on the box above. \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 - 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
