https://youtu.be/ParxdL5gREI General Relativity Seminar Speaker: Prashant Kocherlakota (BHI) Title: Testing spacetime geometry with images of supermassive compact objects: Current status and the future Abstract: Astrophysical black holes (BHs) are expected to be described by the Kerr solution of the Einstein equations. Several frameworks have recently been developed to parametrically deform the Kerr metric in significantly […]

https://youtu.be/0gWCm0wmgOY General Relativity Seminar Speaker: Chiara Toldo (Harvard) Title:Â Near extremal de Sitter black holes and JT gravity Abstract:Â In this talk I will explore the thermodynamic response near extremality of charged black holes in four-dimensional Einstein-Maxwell theory with a positive cosmological constant. The latter exhibit three different extremal limits, dubbed cold, Nariai and ultracold configurations, with […] |
