A model for non-singular black hole collapse and evaporation

Understand

We study the formation of a black hole and its subsequent evaporation in a model employing a minisuperspace approach to loop quantum gravity.

• In previous work the static solution was obtained and shown to be singularity-free.
• Here, we examine the more realistic dynamical case by generalizing the static case with help of the Vaidya metric.
• We track the formation and evolution of trapped surfaces during collapse and evaporation and examine the buildup of quantum gravitationally caused stress-energy preventing the formation of a singularity.
