SUMMARY:General Meeting – May 2024
DESCRIPTION:This is a free and open to the public hybrid event\, held both inperson and online.\nDue to the newly effective insurance requirements\, we regret that we can not allow people under 18 on the Chapman Campus\, they are welcome to attend online.\n Join Zoom\n\nThis meeting’s speaker will present online from Washington\, DC.\n\n  \n  \nData Driven Discovery\n\n  \nIn Evolving Planetary Systems\n\n  \nA Mineral Informatics Approach\n  \n\n  \n  \nThe key to answering many compelling and complex questions in Earth\, planetary\, and life science lies in breaking down the barriers between scientific fields and harnessing the integrated\, multi-disciplinary power of their respective data resources. We have a unique opportunity to integrate large and rapidly expanding data resources\, to enlist powerful analytical and visualization methods\, and to answer multi-disciplinary questions that cannot be addressed by one field alone. \nRapidly expanding mineral data resources have created an opportunity to characterize changes in near-surface mineralogy through deep time and to relate these findings to the geologic and biologic evolution of our planet over the past 4.5 billion years. Data-driven studies employing advanced analytical and visualization techniques such as mineral ecology\, network analysis\, and association analysis\, allow us to begin tackling big questions in Earth\, planetary\, and biosciences\, including those related to (1) the relationships of mineral formation and preservation with large-scale geologic processes\, such supercontinent assembly\, the oxidation of Earth’s atmosphere\, and changes in ocean chemistry. (2) The abundance and likely species of as-yet undiscovered mineral\, as well as the probability of finding a mineral or mineral assemblage at any locality on Earth or another planetary body. (3) Exploring the possibility that Earth’s mineral diversity and distribution is a biosignature. (4) Characterizing the origins of all mineral species through the development of the Evolutionary System of Mineralogy – a system that will provide a framework for predicting the formational conditions of mineral species of unknown origin. (5) Lastly\, integrating across disciplines and exploring ideas that one field alone cannot fully characterize (e.g.\, how the geochemical makeup of our planet affected the emergence and evolution of life\, and\, likewise\, how life influenced chemical composition and geological processes throughout Earth history). \n \nShaunna M. Morrison is a mineralogist and planetary scientist with expertise in crystallography\, crystal chemistry\, and the application of data driven techniques. Morrison is the 4D (Deep Time Data Driven Discovery) Initiative Co-Director at the Carnegie Institution for Science’s Earth and Planets Laboratory\, former Project Manager of the Carnegie led Deep-Time Data Infrastructure (DTDI)\, a Co-Investigator of the CheMin X-ray diffraction instrument on the NASA Mars Science Laboratory (MSL) mission\, a collaborator on the NASA Astrobiology ENIGMA Project\, a Co-Investigator of the NASA Astromaterials Data System\, and a data contributor and collaborator of the RRUFF Project\, including the Mineral Evolution Database (MED)\, and the Evolutionary System of Mineralogy Database (ESMD). Morrison builds on her technical and theoretical background in crystallography\, crystal chemistry\, and martian mineralogy\, to explore new techniques in multidimensional\, multivariate analysis and visualization by employing a range of advanced analytics and machine learning techniques to better understand the complex relationships among Earth and planetary materials\, their formational environments through deep time\, and their coevolution with the biosphere\, including identifying and characterizing mineralogical signs of life. \n  \nViews: 13

SUMMARY:General Meeting – April 2024
DESCRIPTION:This is a free and open to the public hybrid event\, held both inperson and online. Due to the newly effective insurance requirements\, we regret that we can not allow people under 18 on the Chapman Campus\, they are welcome to attend online.\n Join Zoom\n\nThis meeting’s speaker will present online.\n\n  \n  \nHow to Work Amateur Satellites\n  \nwith Your Handheld Radio\n\n  \n \n  \nYou do not need 100W of transmit power nor expensive antenna arrays to work the FM voice amateur satellites! Many hams already have the necessary equipment to “work the birds.” This presentation will walk you through ALL the steps needed to successfully work several ham satellites – including the International Space Station. \n  \nClint K6LCS has been a ham since 1994\, and found his niche in the hobby: working amateur satellites with minimal equipment and telling ALL about it! He has served a liaison between NASA\, the ARISS team\, and schools coordinating amateur radio contacts between the International Space Station and students (and also orchestrated a wildly successful ARISS contact). Audiences have never found his presentation slides “wordy” nor dull. Trivia questions are included throughout the session – audiences are never bored. \nFor reference materials\, Clint has created a support Web site at work-sat.com. The Web site has become a one-stop source for ALL the citations and equipment recommendations and software suggestions made in the presentation. \nProfessionally\, Clint was sales manager for ADI / Premier Communications / Pryme\, worked for a Motorola commercial two-way dealer a couple of years\, and for Ham Radio Outlet a couple more. He resides in Jurupa Valley\, California\, with his wife\, Karen\, and their new addition to the family: Huck\, a two-year-old 75-pound Lab. \n  \nViews: 13

SUMMARY:General Meeting – March 2024
DESCRIPTION:This is a free and open to the public hybrid event\, held both inperson and online.\nDue to the newly effective insurance requirements\, we regret that we can not allow people under 18 on the Chapman Campus\, they are welcome to attend online.\n Join Zoom\n\nThis meeting’s speaker will present online from Waterloo\, Canada.\n\n  \n  \nCosmic Mirages: Seeing Dark Matter\n  \nwith Gravitational Lenses\n\n\n\n\n  \n \n  \n  \nMost of the matter in the Universe is dark matter: an elusive particle that is completely invisible. But we can “see” this matter by studying how it distorts the light from galaxies in the distant Universe\, a phenomenon called gravitational lensing. I will give a whirlwind tour of gravitational lensing’s “greatest hits” showing how it can be used as a tool to understand some of the most mysterious things in the Universe: from black holes to the “cosmic web” of dark matter that links galaxies together. \n  \n \n  \nMike Hudson received his Ph.D. from the Institute of Astronomy\, University of Cambridge in 1993 where studied the expansion of the Universe. He did post-doctoral research work at Durham University and at the University of Victoria in Canada\, where he was a National Fellow of the Canadian Institute of Theoretical Astrophysics.  In 1999\, he moved to the University of Waterloo\, where he is currently Professor. His scientific interests include the nature of dark matter and dark energy\, how the Universe expands\, and how galaxies form and evolve.  He can be found on Twitter as @MikeHudsonAstro \nViews: 13

SUMMARY:General Meeting – February 2024
DESCRIPTION:This is a free and open to the public hybrid event\, held both inperson and online. Due to the newly effective insurance requirements\, we regret that we can not allow people under 18 on the Chapman Campus\, they are welcome to attend online.\n Join Zoom\n\nThis meeting’s speaker will present online from Connecticut.\n\n  \n  \nThe Wild West of Star Formation\n\n  \n  \n \n  \nTonight we saddle up to explore the extreme center of our Milky Way galaxy – a chaotic region containing dense gas\, stars\, and a supermassive black hole. The normal rules for star formation don’t seem to apply here and scientists are chasing down these law-breaking clouds in our Galaxy’s Center. We will explore a multi-wavelength perspective of our Galaxy’s Center and what fuels this extreme region. By understanding what is causing the rules of star formation to break down in this region\, we can better understand how stars are born across the cosmos. \n  \n  \n \n  \nCara Battersby is a PhD astrophysicist with a lifelong passion for education and community outreach. She is currently an associate professor of physics at the University of Connecticut where she leads the Milky Way Laboratory. This research group is funded by NSF and NASA and uses our Milky Way as a laboratory to explore physics across the cosmos\, using both large observational surveys and numerical simulations. Dr. Battersby has authored over 70 publications and given over 50 invited research presentations. She has worked with folks at NASA on developing space mission concepts\, is a co-founder of major outreach programs UConn STARs and BiteScis\, and secretly wants to be Carl Sagan when she grows up. She loves being active outdoors (hiking\, climbing\, etc!)\, playing music and spending time with her wonderful family and friends. \n  \nViews: 13

SUMMARY:General Meeting – January 2024
DESCRIPTION:This is a free and open to the public hybrid event\, held both inperson and online. Due to the newly effective insurance requirements\, we regret that we can not allow people under 18 on the Chapman Campus\, they are welcome to attend online.\n Join Zoom\n\nThis meeting’s speaker will present inperson from the Chapman University’s campus.\n\n  \n  \nThe [2nd] Great North American\n  \n  \nSolar Eclipse\n  \n  \n \n  \nFor the second time in just under seven years\, the United States will experience another total solar eclipse (TSE) — the first such occultation since the total solar eclipse of August 21\, 2017\, which traced a path from the Oregon coastline to Charleston\, South Carolina\, observed by nearly 215 million people. On April 8th of next year\, another TSE will be seen (weather cooperating) in the continental U.S.   This event shall be the last such eclipse visible in the domestically\, until August 23\, 2044\, followed by another TSE on August 12\, 2045. \nLike the 2017 event\, many large cities lie in the path of totality — chief among them being San Antonio\, Dallas-Fort Worth\, Austin\, and Waco\, TX\, as well as Indianapolis\, IN\, Cleveland\, OH\, and Buffalo and Rochester\, NY. \nThe presentation shall focus on the overall circumstances of the April 8th eclipse\, synoptic weather prospects for selected observation venues\, as well as providing some helpful suggestions regarding preparations for those interested in attempting to view totality. \n  \n  \n \nProfessor Joel Harris has been traveling throughout the world to observe solar eclipses since 1973 — totaling 50 years of eclipse chasing\, encompassing some 22 total eclipse events\, and having spent over an hour within the lunar umbra. \nHis first eclipse experience was as part of a scientific team supporting the noted American solar astronomer\, Dr. Donald Menzel of Harvard Observatory\, in the Mauritanian Sahara Desert in 1973. \nProfessor Harris spent 17 years in the defense and aerospace industries as a senior systems engineer\, having earned both his bachelor’s degree in electrical/electronic engineering\, and his master’s in systems engineering. \nHe has been awarded the NASA Group Achievement Award for his public relations work as project information officer supporting the Galileo Project at Jet Propulsion Laboratory from 1982 – 1986\, and was elected a Fellow of the Royal Astronomical Society in 2018. \nHarris currently lives in Newbury Park\, CA\, with his wife of 23 years\, Patti\, their rescue dogs Bailey and Sadie\, and his “B flat Grey Tabby” cat\, Miranda. \nViews: 13

Due to the newly effective insurance requirements\, we regret that we can not allow people under 18 on the Chapman Campus\, they are welcome to attend online.\n Join Zoom\n\nThis meeting’s speaker will present inperson from the Chapman University’s campus.\n\n  \n  \nBrave New Worlds\n  \n  \n \n  \nThirty years ago\, the astronomical world finally had an answer to one of the most profound questions humanity has ever asked: do the distant stars have worlds of their own? In the last three decades\, we have gone from a handful of initial discoveries to an avalanche of information. Internationally published science illustrator and long time OCA member Chris Butler will bring it all together and offer his perspective of where we stand now\, and what the implications are of all these brave new worlds. \n  \n \n  \nChris Butler is an internationally published science and nature artist best known for his work on astronomical subjects and for his work as a science speaker and educator.  Chris is the senior artist and animator for the Griffith Observatory in Los Angeles\, where he has been involved in public program production and exhibit design for 26 years.  Chris has been a member of the Orange County Astronomers since 1984\, and has served as Vice President and a member of the Board. Chris holds memberships in numerous other astronomical organizations\, is a Fellow of the Royal Astronomical Society\, and was honored to have an asteroid named after him by the International Astronomical Union. \nViews: 13

SUMMARY:General Meeting – September 2023
DESCRIPTION:This is a free and open to the public hybrid event\, held both inperson and online. Due to the newly effective insurance requirements\, we regret that we can not allow people under 18 on the Chapman Campus\, they are welcome to attend online.\n Join Zoom\n\nThis meeting’s speaker will present inperson on the campus of Chapman University.\n\n  \n  \n  \nTHE SHAKING COSMOS:\n  \n  \nObserving the Universe in\n  \n  \nGravitational Waves with LISA\n  \n \nVirtually everything we know about the Universe has been discovered from the study of photons — light in all its myriad forms from radio waves\, to visible light\, to x-rays and beyond.  At the dawn of the 21st century\, advanced technology is providing access to the Cosmos through detection of sub-atomic particles like cosmic rays and neutrinos\, and through detection of ripples in the fabric of spacetime itself. \nThese ripples in spacetime\, called gravitational waves\, carry information not in the form of light or particles\, but in the form of gravity itself.  Gravitational waves are messengers which carry the stories of what happens when two black holes collide at the centers of galaxies\, of how the compact stars fall into monstrous black holes\, and of how the graveyard of the galaxy is filled with the quiet whisper of binary white dwarf stars that spiral together ever so slowly as they fade into oblivion. \n \nThis talk will explore the modern description of gravity\, what gravitational waves are and how we hope to measure them\, and what we hope to learn from their detection. We’ll focus on the forthcoming space gravitational wave observatory\, LISA\, being launched in the early 2030s by ESA and NASA. Gravity has a story to tell\, and in this talk\, we’ll explore some of discoveries we hope to make by listening. \n \nShane Larson is a research professor of physics at Northwestern University\, where he is the Associate Director of CIERA (Center for Interdisciplinary Exploration and Research in Astrophysics). He works in the field of gravitational wave astrophysics\, specializing in studies of compact stars\, binaries\, and the galaxy.  He works in gravitational wave astronomy with both the ground-based LIGO project\, and future space-based observatory LISA. He was formerly a tenured associate professor of physics at Utah State University. He is an award winning teacher\, and a Fellow of the American Physical Society. He contributes regularly to a public science blog at writescience.wordpress.com\, and tweets with the handle @sciencejedi \nViews: 13

SUMMARY:General Meeting – August 2023
DESCRIPTION:This is a free and open to the public hybrid event\, held both inperson and online. Due to the newly effective insurance requirements\, we regret that we can not allow people under 18 on the Chapman Campus\, they are welcome to attend online.\n Join Zoom\n\nThis meeting’s speaker will present online from Heidelberg\, Germany.\n\n  \n  \n  \nA Journey Through Binary Black Holes\n  \n \n  \nThe zoo of binary black holes has never been so rich. Before the first LIGO-Virgo detection of gravitational waves in 2015\, we could only speculate about the existence of binary black holes\, i.e. systems composed of two black holes orbiting about each other. Now\, the number of detected binary black holes approaches the 100 mark\, and we expect many new discoveries in the next few months. The mass of the black holes observed by LIGO and Virgo ranges from a few up to a few hundred times the mass of our Sun. Some of them are relatively nearby\, others merged several Billion years ago and their gravitational wave signal reached us from far away. In this talk\, we will explore the main properties of binary black holes and discuss their main formation channels and open questions. \n\n\n\n  \nMichela Mapelli obtained her PhD in Astrophysics from the International School for Advanced Studies (SISSA/ISAS\, Trieste\, Italy) in 2006. She then moved to Zurich (Switzerland) for a postdoctoral fellowship. In 2010\, she got a permanent research position at the Italian National Institute for Astrophysics (INAF)\, where she built her first research group focused on the study of black holes of different sizes. After holding a professorship at the University of Innsbruck (Austria\, 2017-2018) and Padova (Italy\, 2018-2023)\, she recently became Full Professor of Computational Physics at the University of Heidelberg (Germany). During her career\, she obtained several prizes for her research on black holes\, including the MERAC Prize 2015 for the Best Early Career Researcher in Theoretical Astrophysics and a Consolidator Grant of the European Research Council. In 2009\, several years before the first gravitational-wave detection\, she proposed the formation of black holes with mass about 30-50 times the mass of our Sun. She is now an enthusiastic member of the LIGO-Virgo-KAGRA collaboration and is planning for the next-generation gravitational-wave detectors. \nViews: 13

DESCRIPTION:This is a free and open to the public hybrid event\, held both inperson and online. Due to the newly effective insurance requirements\, we regret that we can not allow people under 18 on the Chapman Campus\, they are welcome to attend online.\n Join Zoom\n\n\n  \n  \n  \nThrowing DART(s) at Asteroids\n  \n  \nNASA’s First Planetary Defense Mission\n  \n \n  \nOn September 26\, 2022\, NASA intentionally smashed the DART spacecraft into an asteroid as humanity’s first test mission for planetary defense. The Double Asteroid Redirection Test (DART) spacecraft’s collision with its target asteroid\, which poses no threat to Earth\, changed the asteroid’s motion in a way that can be measured using ground-based telescopes\, including those of Las Cumbres Observatory. \n\nIn this talk\, Dr. Tim Lister will describe near-Earth asteroids\, impact hazards\, and what the DART mission will do to prepare for potentially deflecting asteroids in the future. \n  \n  \nDr Tim Lister joined Las Cumbres Observatory (LCO) as a project scientist in 2007 and is now a Staff Scientist. He specializes in the observation and characterization of small Solar System bodies\, particularly comets and Near Earth Asteroids. He received a M. Sci in Astrophysics from the University of St Andrews in 1997 and a Doctorate in Astrophysics on the study of magnetic activity on variable stars in 2000\, also from the University of St Andrews. Following his doctorate\, he was a founding member of the\nSuperWASP transit survey searching for extrasolar planets\, specializing in building data processing pipelines for analyzing the survey data\, for which he received the RAS Group Achievement Award. Since joining LCO\, he has worked on building pipelines and data archives for the observatory\, confirming new transiting extrasolar planets and building a new science group for the study of Solar System objects. In the course of this research\, he has developed web-based software to allow the scheduling and analysis of observations of Solar System objects using the telescopes of the LCO Network. He is currently Co-lead of the LCO Outbursting Objects Key (LOOK) Project to study the behavior of comets for ESA’s Comet Interceptor mission and a member of NASA’s Double Asteroid Redirection Test (DART) Investigation Team. \nViews: 13

There is a supermassive black hole at the center of the Galaxy.\nBeyond its sphere of influence\, there is a rich environment revealing relic of past activities of the black hole.\nAs part of an international team\, observations with the new South African MeerKAT observatory has discovered hundreds of\nmagnetized thread-like filaments in the inner 1000 light years of the region surrounding the black hole at the Galactic center. These filaments appear\nharp-like\, commentary tail-like\, or loop-like structures. After a brief history of the discovery of radio filaments in\nthe 80’s\, the nature and origin of these structures will be discussed with an emphasis of why it is so puzzling\nto understand their origin. \n  \n \nF. Zadeh received his PhD in Astronomy from Columbia University in 1986 before he went to NASA/Goddard Space Flight center as a National Research Council postdoc. He then joined the department of physics and astronomy at Northwestern University in 1989 and has been there since. His research interests are the black hole at the center of the Galaxy\, star formation and cosmic-ray physics. \nViews: 13

Due to the newly effective insurance requirements\, we regret that we can not allow people under 18 on the Chapman Campus\, they are welcome to attend online.\n Join Zoom\n\n\n  \n  \n  \nHunting Isolated Black Holes\n  \n  \n \n  \nBlack holes are fascinating\, but enigmatic celestial objects.  Long predicted by theory\, as the product of some of the most energetic events in the universe\, they have always presented severe challenges to observational astronomers.  If the have a binary companion\, accretion or the gravitational waves released during a merger can reveal their presence\, but isolated black holes offer no such signatures.  Yet understanding the Milky Way’s population of stellar remnants – both isolated and binary – will place important constraints on models of stellar evolution.  The phenomenon of microlensing provides the means to   detect massive objects\, even when they emit no light at all.  Modern surveys are capable of detecting these transient events across a huge swathe of the Galaxy\, and will chart the population of stellar remnants in the Milky Way.  This talk will explore how black holes fit into our understanding of the lives of massive stars\, how microlensing can reveal even singleton stellar remnants\, and describe how recent work has confirmed the first such discovery. \nMore on microlensing: http://www.microlensing-source.org/ \n  \n  \n \nDr. Rachel Street completed her Ph.D. at the University of St. Andrews in Scotland\, where her thesis focused on searching for exoplanets in open clusters.  This work led to her first post-doctoral position at Queen’s University Belfast\, Northern Ireland\, where she was a founder member of the SuperWASP transit survey\, for which she received the RAS Group Achievement Award and a PPARC Postdoctoral Fellowship.  Rachel considers herself fortunate to have joined Las Cumbres Observatory (LCO)\, soon after it was founded\, giving her the opportunity to watch the LCO Telescope Network develop into full operation.  Rachel started to study first exoplanets and later stellar remnants through the phenomenon of microlensing using LCO’s telescopes\, and she now leads the LCO Microlensing group as a Senior Scientist.  Rachel recently stepped down as a co-chair of the Rubin Observatory Transients and Variable Stars Science Collaboration\, which aims to prepare for groundbreaking science with the Legacy Survey of Space and Time. \n  \nViews: 13
