An outstanding problem in gravitation theory and relativistic astrophysics today is to
understand the final outcome of an endless gravitational collapse. Such a continual collapse …

Generalizing earlier results on the initial data and the final fate of dust collapse, we study
here the relevance of the initial state of a spherically symmetric matter cloud towards …

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 …

We consider the consequences of applying general relativity to the description of the
dynamics of a galaxy, given the observed flattened rotation curves. The galaxy is modeled …

By using the most general form of Einstein equations for General Relativistic (GTR) spherical
collapse of an isolated fluid having arbitrary equation of state and radiation transport …

We consider a Lemaitre-Tolman-Bondi type space-time in Einstein gravity with the Gauss-
Bonnet combination of quadratic curvature terms, and present an exact solution in closed …

The general exact solution describing the dynamics of anisotropic elastic spheres supported
only by tangential stresses is reduced to a quadrature using Ori's mass-area coordinates …

This article gives an elementary review of gravitational collapse and the cosmic censorship
hypothesis. Known models of collapse resulting in the formation of black holes and naked …

We critically review here the concepts which gave rise to the Black Hole (BH) paradigm over
almost past 90 years. First we point out that the very attempt to find the spacetime around a …

Following our recent finding [1] that, for the final state of continued spherical gravitational
collapse of sufficiently massive bodies, the final gravitational mass of the fluid M ƒ→ 0, we …
