Gravitational collapse from smooth initial data with vanishing radial pressure
Ashutosh Mahajan, Rituparno Goswami, Pankaj S. Joshi
We study here the spherical gravitational collapse assuming initial data to be necessarily smooth, as motivated by the requirements based on physical reasonableness. A tangential p…
Black hole formation in perfect fluid collapse
Rituparno Goswami, Pankaj S Joshi
We construct here a special class of perfect fluid collapse models which generalizes the homogeneous dust collapse solution in order to include non-zero pressures and inhomogeneiti…
The critical role of shear in gravitational collapse
Pankaj S. Joshi, Rituparno Goswami, Naresh Dadhich
We investigate here how the shearing effects present within a collapsing matter cloud influence the outcome of gravitational collapse in terms of formation of either a black hole o…
