Constraining alternatives to the Kerr black hole

no code implementations8 Feb 2021 Rajibul Shaikh, Kunal Pal, Kuntal Pal, Tapobrata Sarkar

We conclude that these black hole alternatives having $r_0$ below this maximum range (i. e. $r_0\leq r_{0, max}$) is consistent with the size and deviation from circularity of the observed shadow of M87$^{*}$.

Disformal transformations and the motion of a particle in semi-classical gravity

no code implementations14 Jan 2021 Sandip Chowdhury, Kunal Pal, Kuntal Pal, Tapobrata Sarkar

The approach to incorporate quantum effects in gravity by replacing free particle geodesics with Bohmian non-geodesic trajectories has an equivalent description in terms of a conformally related geometry, where the motion is force free, with the quantum effects inside the conformal factor, i. e., in the geometry itself.
