C04.00002: Chandra Explores Sagittarius A*'s Event Horizon Dynamics: X-ray and Multi-wavelength Variability Invited Speaker: Daryl Haggard The last century has seen exciting tests of general relativity and the LIGO-Virgo observatories have now definitively discovered black holes. And yet we are only beginning to approach the event horizon with electromagnetic observations. Sagittarius A* is one of the closest supermassive black holes targeted by the Chandra X-ray Observatory, as well as VLT's GRAVITY instrument, the Event Horizon Telescope, and many more. It thus offers an exciting opportunity for coordinated, multi-wavelength campaigns, which are poised to identify the origin of observed X-ray and IR variability, connect it to horizon-scale structure in the submm, and distinguish between competing models: hot spots, inflow/outflow, reconnection regions, shocks, or even magnetosphere gaps. I will review recent highlights from Chandra and multi-wavelength observations of Sgr A* and prospects for future discovery. |

C04.00003: The Chandra View of Supernovae and Supernova Remnants Invited Speaker: Carles Badenes I will review the most salient observations of Supernovae and Supernova Remnants made by Chandra during the 20 years that have elapsed since its launch. I will touch briefly on very diverse topics, including neutron stars, pulsar wind nebulae, particle acceleration in shocks, X-ray searches for prompt supernova emission, and supernova progenitor studies from supernova remnant observations. I will put special emphasis on the main results obtained for both core collapse and Type Ia supernova progenitors thanks to the unique capabilities of Chandra, and I will outline the key contributions that the mission can make to this field of research in the near future. |
