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…
A novel gravitational lensing feature by wormholes
Rajibul Shaikh, Pritam Banerjee, Suvankar Paul +1
Horizonless compact objects with light rings (or photon spheres) are becoming increasingly popular in recent years for several reasons. In this paper, we show that a horizonless ob…
