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…
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…
Shadow of nulllike and timelike naked singularities without photon spheres
Dipanjan Dey, Rajibul Shaikh, Pankaj S. Joshi
In this paper, we derive general conditions for a shadow to occur, without a photon sphere in a spacetime, caused by central nulllike or timelike naked singularities. Using these c…
Constraining modified gravity from tidal phenomena in binary stars
Pritam Banerjee, Debojyoti Garain, Suvankar Paul +2
In beyond-Horndeski theories of gravity, the Vainshtein screening mechanism might only be partially effective inside stellar objects. This results in a modification of the pressure…
Perihelion Precession and Shadows near Blackholes and Naked Singularities
Dipanjan Dey, Rajibul Shaikh, Pankaj S. Joshi
It is now known that, apart from black holes, some naked singularities can also cast shadows which provide their possible observable signatures. We examine the relevant question he…
