SUMMARY:General Meeting – July 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  \nTips and Secrets on Planetary Imaging\n  \n  \nThis talk will discuss the preparation\, imaging capture and processing for Planetary Imaging. \n \nChristopher Go lives on the island of Cebu in the Philippines. He has been an amateur astronomer since 1986\, the year of the return of Halley’s Comet. He studied at the University of San Carlos where he received a BS in physics. \nStarting as an amateur astronomer with a pair of 10×40 binoculars\, Chritopher Go would later own several different telescopes. He currently uses a Celestron C14 for planetary imaging. \nChris’s main astronomical interests are planetary imaging\, particularly of Jupiter and Saturn. \nIn February 2006\, Christopher Go discovered that the white spot Oval BA of Jupiter (later called Red Spot Jr.) had turned red. He joined planetary scientists Imke de Pater and Phil Marcus to observe Jupiter in the spring of 2006 with the Hubble Space Telescope. He was also involved with follow-up Hubble and Keck telescope observations of Jupiter. \nIn 2008\, he received the Association of Lunar and Planetary Observers’ prestigious Walter Haas Award. In June 3\, 2010\, he confirmed the Jupiter Impact that was observed by Anthony Wesley. Asteroid 2000 EL157 has been named 30100Christophergo\, in his honour. \nViews: 4

SUMMARY:General Meeting – June 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\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: 4

SUMMARY:General Meeting – May 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\n\n  \n  \n  \nThe Mystery Behind the Origin of\n  \n  \nRadio Filaments in our Milky Way Galaxy\n  \n  \n \n  \nThe Galactic center is an active region of our Milky Way Galaxy. 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: 4

SUMMARY:General Meeting – March 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\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: 4

SUMMARY:General Meeting – February 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\n\n  \n  \n  \nPuzzles in Galaxy Evolution\n  \n  \n  \n \nI will describe a pair of sharp puzzles suggesting a possible mismatch between our theory of galaxy evolution and recent observations from the James Webb Space Telescope (JWST). First\, current models predict that most distant galaxies found by JWST should be seen at a time when they are transitioning from the initial assembly of their ingredients to the later processes by which they form stars\, and other structures we recognize as a galaxy.  Instead\, fully-formed\, massive galaxies appear to exist impossibly early\, before their ingredients should even have been able to assemble.  Second\, a possible explanation for this would be that most galaxies grow very differently from the processes we have observed in star-forming regions of our own Milky Way.  I will discuss whether such a difference might be able to reconcile both problems\, or whether something is still “broken”. \n \nCharles Steinhardt is an associate professor at the Cosmic Dawn Center and University of Copenhagen\, having previously spent time at Caltech\, Kavli IPMU\, Harvard\, and Princeton.  His research is inspired by astrophysical phenomena whose explanation has been cast into doubt\, either by new theoretical ideas or new observations.  Recently\, this includes several different areas of astronomy and astrophysics\, including galaxy evolution\, black hole accretion\, and gamma-ray bursts.  Recent work also includes developing machine learning and statistical methods for making full use of the large datasets modern astronomy produces.  He also runs a summer undergraduate research program that brings American students to Copenhagen each summer. \nViews: 4
