SUMMARY:The Galactic Underworld: Finding Invisible Black Holes
DESCRIPTION:The Leonard E. Parker Center for Gravitation\, Cosmology & Astrophysics invites you to explore the dark side of our Galaxy with Professor Kareem El-Badry of the California Institute of Technology. \nBlack holes are among the most fascinating objects in the Universe\, yet most of them are completely invisible. So how do astronomers find them? Learn how the Gaia mission is revolutionizing our view of the Milky Way by measuring the motions of more than a billion stars with extraordinary precision. These measurements allow us to detect the subtle gravitational pull of unseen companions—including black holes that emit no light at all. We’ll discuss the discovery of Gaia BH1\, the first unambiguous dormant stellar-mass black hole found in the Milky Way\, and how discoveries like it are changing our understanding of how stars live\, die\, and produce black holes. We’ll also discuss how the imminent NASA Nancy Grace Roman Space Telescope mission will carry Gaia’s work forward and even discover isolated black holes. \nKareem El-Badry is an Assistant Professor of Astronomy at the California Institute of Technology and a 2025 MacArthur Fellow. His research focuses on the formation and evolution of stars and compact objects\, particularly black holes\, neutron stars\, and white dwarfs in binary systems. He uses large astronomical surveys—including the European Space Agency’s Gaia mission—to discover rare stellar systems and to better understand how massive stars end their lives. \nPlease reserve your free spot for this event by September 8\, 2026 at https://forms.gle/hfZtmX1fa9R15dBo6
