Superradiance and stability of rotating charged black holes in T-duality
Sohan Kumar Jha, Kimet Jusufi
We investigate the shadow images, the relation between Quasinormal Modes (QNMs) and the shadow radius, and the superradiance effect observed in the context of a rotating charged bl…
Shadow, quasinormal modes, greybody bounds, and Hawking sparsity of Loop Quantum Gravity motivated non-rotating black hole
Sohan Kumar Jha
We consider Loop Quantum Gravity(LQG) motivated polymerized black hole and study shadow, quasinormal modes, and Hawking radiation. We obtain analytical expressions of photonsp…
Study of quasinormal modes, greybody bounds, and sparsity of Hawking radiation within the metric-affine bumblebee gravity framework
Sohan Kumar Jha, Anisur Rahaman
We consider a static and spherically symmetric black hole metric that emerges from the vacuum solution of the traceless metric-affine bumblebee model. Our study focuses on the poss…
Photonsphere, shadow, quasinormal modes, and greybody bounds of non-rotating Simpson-Visser black hole
Sohan Kumar Jha
In this manuscript, we study photonsphere, shadow, quasinormal modes, Hawking temperature, and greybody bounds of a non-rotating Simpson-Visser black hole which is a regular black…
Superradiance scattering of scalar, electromagnetic, and gravitational fields and thin accretion disk around non-commutating Kerr black hole
Sohan Kumar Jha
We consider the non-commutative(NC) Kerr black hole where the mass of the central object is smeared over a region of linear size , is the strength of the NC character…
