Open AccessRegularizing the JNW and JMN naked singularities
We extend the method of Simpson and Visser (SV) of regularizing a black hole spacetime, to cases where the initial metric represents a globally naked singularity. We choose two particular geometries, the Janis...

Open AccessDisformal transformations and the motion of a particle in semi-classical gravity
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, wher...

Open AccessCollapse in f(R) gravity and the method of R matching
Collapsing solutions in f(R) gravity are restricted due to junction conditions that demand continuity of the Ricci scalar and its normal derivative across the time-like collapsing hypersurface. These are obtained...
