SUMMARY:General Meeting – October 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 Flagstaff\, Arizona.\n\n  \n  \nThe Discovery of Pluto\n  \n \n  \n  \nThe search for\, and eventual discovery of\, Pluto is a colorful tale of dedication\, perseverance. and personal triumph. It was a real needle-in-haystack effort that is as much about the human spirit as it is scientific pursuits. \n \n  \nKevin Schindler is the historian at Lowell Observatory – where he has worked for 28 years – and an active member of the Flagstaff history and science communities. He has written more than 600 magazine and newspaper articles on subjects ranging from local history and astronomy to baseball and the Lincoln Memorial\, and contributes a bi-weekly astronomy column\, “View from Mars Hill”\, for the Arizona Daily Sun newspaper. He has written seven books\, including Historic Tales of Flagstaff (written with Mike Kitt). Fun fact: Kevin has both a fossil crab and asteroid named after him. \nViews: 1

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: 1

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: 1

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: 1

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: 1

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: 1
