Tidal disruption near black holes and their mimickers
Pritam Banerjee, Suvankar Paul, Rajibul Shaikh +1
Black holes and wormholes are solutions of Einstein's field equations, both of which, from afar, look like a central mass. We show here that although at large distances both behave…
Observational signatures of wormholes with thin accretion disks
Suvankar Paul, Rajibul Shaikh, Pritam Banerjee +1
We numerically construct images of thin accretion disks in rotating wormhole backgrounds, for the Kerr-like and the Teo class of wormholes. Our construction is illustrated by two m…
Can we distinguish black holes from naked singularities by the images of their accretion disks?
Rajibul Shaikh, Pankaj S. Joshi
We study here images of thin accretion disks around black holes and two classes of naked singularity spacetimes and compare these scenarios. The naked singularity models which have…
Black hole shadow in a general rotating spacetime obtained through Newman-Janis algorithm
Rajibul Shaikh
The Newman-Janis (NJ) algorithm has been extensively used in the literature to generate rotating black hole solutions from nonrotating seed spacetimes. In this work, we show, using…
Analytical approach to strong gravitational lensing from ultracompact objects
Rajibul Shaikh, Pritam Banerjee, Suvankar Paul +1
Strong gravitational lensing from black holes results in the formation of relativistic images, in particular, relativistic Einstein rings. For objects with event horizons, the radi…
Tidal effects away from the equatorial plane in Kerr backgrounds
Pritam Banerjee, Suvankar Paul, Rajibul Shaikh +1
We study tidal effects on self-gravitating Newtonian stars rotating around a Kerr black hole in stable circular orbits away from the equatorial plane. Such cases are exemplified by…
