Shadows in conformally related gravity theories
Kunal Pal, Kuntal Pal, Rajibul Shaikh +1
Null geodesics are invariant under a conformal transformation, and thus it might seem natural to assume that the observables corresponding to the shadow of a space-time are also co…
Thin accretion disks around traversable wormholes
Farook Rahaman, Tuhina Manna, Rajibul Shaikh +3
In this paper, we aim to investigate various physical properties and characteristics of radiation emerging from the surface of accretion disks, in a rotating traversable axially sy…
Shadows of Lorentzian traversable wormholes
Farook Rahaman, Ksh. Newton Singh, Rajibul Shaikh +2
The prospect of identifying wormholes by investigating the shadows of wormholes constitute a foremost source of insight into the evolution of compact objects and it is one of the e…
Shadows and thin accretion disk images of the -metric
Rajibul Shaikh, Suvankar Paul, Pritam Banerjee +1
The -metric is a static, axially-symmetric singular solution of the vacuum Einstein's equations without an event horizon. This is a two-parameter family of solutions, generic va…
A stellar constraint on Eddington-inspired Born-Infeld gravity from cataclysmic variable binaries
Pritam Banerjee, Debojyoti Garain, Suvankar Paul +2
Eddington-inspired Born-Infeld gravity is an important modification of Einstein's general relativity, which can give rise to non-singular cosmologies at the classical level, and av…
Constraining alternatives to the Kerr black hole
Rajibul Shaikh, Kunal Pal, Kuntal Pal +1
The recent observation of the shadow of the supermassive compact object M87 by the Event Horizon Telescope (EHT) collaboration has opened up a new window to probe the strong gr…
