Regular Black Holes: Towards a New Paradigm of Gravitational Collapse
Cosimo Bambi
Black holes are one of the most fascinating predictions of general relativity. They are the natural product of the complete gravitational collapse of matter and today we have a bod…
Testing the -Kerr metric with black hole X-ray data
Jiahao Tao, Shafqat Riaz, Biao Zhou +3
The spacetime around astrophysical black holes is thought to be described by the Kerr solution. However, even within general relativity, there is not yet a proof that the final pro…
Horizon-scale tests of gravity theories and fundamental physics from the Event Horizon Telescope image of Sagittarius A
Sunny Vagnozzi, Rittick Roy, Yu-Dai Tsai +12
Horizon-scale images of black holes (BHs) and their shadows have opened an unprecedented window onto tests of gravity and fundamental physics in the strong-field regime. We conside…
RELXILL_NK: A Black Hole Relativistic Reflection Model for Testing General Relativity
Askar B. Abdikamalov, Dimitry Ayzenberg, Cosimo Bambi +1
In this paper, we briefly present RELXILL_NK, the first and currently only readily available model of the relativistic reflection spectrum of black hole accretion disks that includ…
Gravitational lensing for a boosted Kerr black hole in the presence of plasma
Carlos A. Benavides-Gallego, A. A. Abdujabbarov, Cosimo Bambi
We obtain the deflection angle for a boosted Kerr black hole in the weak field approximation. We also study the behavior of light in the presence of plasma by considering different…
Weak gravitational lensing: a compact object with arbitrary quadrupole moment immersed in plasma
Hrishikesh Chakrabarty, Askar B. Abdikamalov, Ahmadjon A. Abdujabbarov +1
We study weak gravitational lensing around a compact object with arbitrary quadrupole moment in the presence of plasma. The studied compact objects are considered to be spherically…
