Universal Bounds on Black Hole Observables Imposed by Energy Conditions
Rahul Kumar Walia, Boris Georgiev, Chi-kwan Chan
We establish a universal connection between the classical energy conditions and directly observable black hole properties. By imposing the energy conditions locally at the photon s…
Influence of Observer Inclination and Spacetime Structure on Photon Ring Observables
Kiana Salehi, Rahul Kumar Walia, Dominic Chang +1
Recent observations of the near-horizon regions of BHs, particularly the images captured by the Event Horizon Telescope (EHT) collaboration, have greatly advanced our understanding…
Spacetime Measurements with the Photon Ring
Rahul Kumar Walia, Prashant Kocherlakota, Dominic O. Chang +1
We explore the universal symmetries of the black hole photon ring in a wide range of non-Kerr spacetimes, including the Kerr-Newman, Kerr-Sen, Kerr-Bardeen, and Kerr-Hayward metric…
