Item On naked singularities in higher dimensional Vaidya space-times(2001-04-03) Ghosh, S. G.; Dadhich, NareshWe investigate the end state of gravitational collapse of null fluid in higher di- mensional space-times. Both naked singularities and black holes are shown to be developing as final outcome of the collapse. The naked singularity spectrum in col- lapsing Vaidya region (4D) gets covered with increase in dimensions and hence higher dimensions favor black hole in comparison to naked singularity. The Cosmic Censor- ship Conjecture will be fully respected for a space of infinite dimensionItem Why do naked singularities form in gravitational(2002-03-12) Joshi, P. S.; Dadhich, Naresh; Roy, MaartensWe investigate what are 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 sufficiently strong shearing effects near the singularity delay the formation of the apparent horizon. This exposes the singularity to an external observer, in contrast to a black hole, which is hidden behind an event horizon due to the early formation of an apparent horizonItem On naked singularities in higher dimensional Vaidya space-times(2000-08-16) Ghosh, S.
