Nonsingular black hole evaporation and "stable" remnants.
We examine the evaporation of two–dimensional black holes, the classical space–times of which are extended geometries, like for example the two–dimensional section of the extremal Reissner–Nordstrom black hole. We find that the evaporation in two particular models proceeds to a stable end–point. This should represent the generic behavior of a certain class of two–dimensional dilaton–gravity mod...

متن کاملStability of a vacuum nonsingular black hole
This is the first of series of papers in which we investigate stability of the spherically symmetric space-time with de Sitter center. Geometry, asymptotically Schwarzschild for large r and asymptotically de Sitter as r → 0, describes a vacuum nonsingular black hole for m ≥ mcr and particle-like self-gravitating structure for m < mcr where a critical value mcr depends on the scale of the symmet...
متن کاملBlack hole mass threshold from nonsingular quantum gravitational collapse.
Quantum gravity is expected to remove the classical singularity that arises as the end state of gravitational collapse. To investigate this, we work with a toy model of a collapsing homogeneous scalar field. We show that nonperturbative semiclassical effects of loop quantum gravity cause a bounce and remove the black hole singularity. Furthermore, we find a critical threshold scale below which ...
متن کاملEnergy associated with a static spherically symmetric nonsingular black hole
We evaluate the energy distributions of the Dymnikova space-time using the Weinberg, Papapetrou, and Møller energy-momentum complexes. This result sustain the importance of the energy-momentum complexes in the evaluation of the energy distribution of a given space-time. To compare the energy distributions obtained by using several definitions, these results show that the Einstein, Tolman, and W...
