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…
Exact Quantum State of Collapse and Black Hole Radiation
Cenalo Vaz, Louis Witten, T. P. Singh
We construct an exact quantum gravitational state describing the collapse of an inhomogeneous spherical dust cloud using a lattice regularization of the Wheeler-DeWitt equation. In…
A note on the thermodynamics of gravitational radiation
T. Padmanabhan, T. P. Singh
It is shown that linearized gravitational radiation confined in a cavity can achieve thermal equilibrium if the mean density of the radiation and the size of the cavity satisfy cer…
