Lense-Thirring effect and precession of timelike geodesics in slowly rotating black hole and naked singularity spacetimes
Parth Bambhaniya, Jay S. Verma, Dipanjan Dey +2
In this paper, we investigate the properties of the Lense-Thirring precession frequency and periastron precession of the relativistic bound orbits in slowly rotating naked singular…
Comparing Shadows of Blackhole and Naked Singularity
Kanwar Preet Kaur, Pankaj S. Joshi, Dipanjan Dey +2
It is now theoretically well established that not only a black hole can cast shadow, but other compact objects such as naked singularities, gravastar or boson stars can also cast s…
Post-Newtonian properties of EMRI with Power Law Potential
Chinmay N. Gandevikar, Divyesh N. Solanki, Dipanjan Dey
There are many astrophysical scenarios where extreme mass ratio inspiral (EMRI) binaries can be surrounded by matter distribution. The distribution of mass can affect the dynamical…
Towards an observational test of black hole versus naked singularity at the galactic center
Dipanjan Dey, Pankaj S. Joshi, Ashok Joshi +1
While the event horizon of a black hole could cast a shadow that was observed recently, a central singularity without horizon could also give rise to such a feature. This leaves us…
Shadows and negative precession in non-Kerr spacetime
Parth Bambhaniya, Dipanjan Dey, Ashok B. Joshi +3
It is now known that the shadow is not only the property of a black hole, it can also be cast by other compact objects like naked singularities. However, there exist some novel fea…
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…
