Abstract:

New horizon-scale images of the Galactic Center black hole Sagittarius A* (Sgr A*) recently published by the Event Horizon Telescope (EHT) allow for new strong-field tests of the Kerr metric in a previously unexplored regime.  I will discuss the recent EHT observations of Sgr A* with a particular focus on how these new results can be used to test fundamental physics. I will briefly touch upon the earlier M87 results as well.

Bio:

Dr. Medeiros is a computational high-energy astrophysicist interested in compact objects. She completed her undergraduate education at the University of California-Berkeley in Physics and Astrophysics, then received her Masters and PhD in Physics from the University of California-Santa Barbara. During her PhD, she spent three years at the Steward Observatory at The University of Arizona and one year at the Black Hole Initiative at Harvard. Dr. Medeiros then went on to an NSF Astronomy and Astrophysics Postdoctoral Fellowship, and is currently a 5-year member of the IAS at Princeton.
