Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

It is now known that when a massive star collapses under the force of its own gravity, the
final fate of such a continual gravitational collapse will be either a black hole or a naked …

Using the concept of cracking we explore the influence that density fluctuations and local
anisotropy have on the stability of local and non-local anisotropic matter configurations in …

The full set of equations governing the structure and the evolution of self-gravitating
spherically symmetric dissipative fluids with anisotropic stresses is written down in terms of …

The full set of equations governing the evolution of self-gravitating spherically symmetric
dissipative fluids with anisotropic stresses is deployed and used to carry out a general study …

We develop here a new procedure within Einstein's theory of gravity to generate equilibrium
configurations that result as the final state of gravitational collapse from regular initial …

We investigate the key physical features that cause the development of a naked singularity,
rather than a black hole, as the end state of spherical gravitational collapse. We show that …

In the study of self-gravitating systems there are three factors whose relevance has been
recurrently and separately stressed in the literature. These are, the Weyl tensor, the local …

We study the motion of test particles in the gravitational field of a Schwarzschild black hole
surrounded by a spherical dark matter cloud with nonzero tangential pressure, and compute …

Gravitational collapse is one of the most fruitful subjects in gravitational physics. It is well
known that singularity formation is inevitable in complete gravitational collapse. It was …
