The discovery of the Universe's late-time acceleration and dark energy has led to a great
deal of research into cosmological singularities, and in this brief review, we discuss all the …

We study here images of thin accretion disks around black holes and two classes of naked
singularity spacetimes and compare these scenarios. The naked singularity models which …

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 …

While the event horizon of a black hole could cast a shadow that was observed recently, a
central singularity without horizon could also give rise to such a feature. This leaves us with …

In this paper, we derive the solutions of orbit equations for a class of naked singularity
spacetimes and compare these with timelike orbits, that is, particle trajectories in the …

On the role of density inhomogeneity and local anisotropy in the fate of spherical collapse
Page 1 5 January 1998 Physics Letters A 237 ( 1998) 113-l 18 PHYSICS LETTERS A On the …

We give a model of the higher-dimensional spherically symmetric gravitational collapse of a
dust cloud including the perturbative effects of quantum gravity. The n (≥ 5)-dimensional …

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 …

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 …
