Geodesics of the hyperbolically symmetric black hole
L. Herrera, A. Di Prisco, J. Ospino +1
We carry out a systematic study on the motion of test particles in the region inner to the horizon of a hyperbolically symmetric black hole. The geodesic equations are written and…

A Time-Like Naked Singularity
Rituparno Goswami, Pankaj S. Joshi, Cenalo Vaz +1
We construct a class of spherically symmetric collapse models in which a naked singularity may develop as the end state of collapse. The matter distribution considered has negative…

Exact Quantum State of Collapse and Black Hole Radiation
Cenalo Vaz, Louis Witten, T. P. Singh
We construct an exact quantum gravitational state describing the collapse of an inhomogeneous spherical dust cloud using a lattice regularization of the Wheeler-DeWitt equation. In…
