On physical insignificance of null naked singularities
Shrirang S. Deshingkar
In this work we study collapse of a general matter in a most general spacetime i.e., a spacetime with any matter and without (assuming) any symmetry. We show that the energy is com…
Can we see naked singularities?
Shrirang S. Deshingkar
We study singularities which can form in a spherically symmetric gravitational collapse of a general matter field obeying weak energy condition. We show that no energy can reach an…
Accurate extraction of the News
Shrirang S. Deshingkar
We propose a new scheme for extracting gravitational radiation from a characteristic numerical simulation of a spacetime. This method is similar in conception to our earlier work b…
New approach to calculating the News
Nigel T. Bishop, Shrirang S. Deshingkar
We consider the problem of finding the gravitational radiation output, or news, within the context of a numerical simulation of a spacetime by means of the null-cone, or characteri…
Appearance of the central singularity in spherical collapse
S. S. Deshingkar, P. S. Joshi, I. H. Dwivedi
We analyze here the structure of non-radial nonspacelike geodesics terminating in the past at a naked singularity formed as the end state of inhomogeneous dust collapse. The spectr…
A Tolman-Bondi-Lemaitre Cell-Model for the Universe and Gravitational Collapse
A. Chamorro, S. S. Deshingkar, I. H. Dwivedi +1
A piecewise Tolman-Bondi-Lemaitre (TBL) cell-model for the universe incorporating local collapsing and expanding inhomogeneities is presented here. The cell-model is made up of TBL…
