QNMs of charged black holes in AdS spacetime: a geometrical optics perspective
Shubham Kala, Anik Rudra, Hemwati Nandan
We investigate the quasinormal modes of the ReissnerNordström antide Sitter black hole using the Penrose limit, motivated by the geometrical optics approximation. This approa…
Energy extraction and particle acceleration around a rotating dyonic black hole in , gauged supergravity
Anik Rudra, Hemwati Nandan, Radouane Gannouji +2
In the present paper, we explore various gravitational aspects such as energy extraction (via the Penrose process and Superradiance), particle collisions around a ,…
Analytic solutions of the geodesic equation for Reissner-Nordström-(anti-)de Sitter black holes surrounded by different kinds of regular and exotic matter fields
Arindam Kumar Chatterjee, Kai Flathmann, Hemwati Nandan +1
The purpose of this study is the derivation of the equation of motion for particles and light in the spacetime of Reissner-Nordström-(anti-)de Sitter black holes in the background…
