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…
Strong gravitational lensing by wormholes
Rajibul Shaikh, Pritam Banerjee, Suvankar Paul +1
We study strong gravitational lensing by a class of static wormhole geometries. Analytical approaches to the same are developed, and the results differ substantially from strong le…
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…
