Description
Arguments from general relativity and quantum field theory suggest that black holes evaporate through Hawking radiation, but without a full quantum treatment of gravity the endpoint of the process is not yet understood. Two dimensional, semi-classical theories of gravity can be useful as toy models for studying black hole dynamics and testing predictions of quantum gravity. Of particular interest are non-singular black holes, since quantum gravity is expected to resolve the singularities that are pervasive in general relativity. This talk will present a general model of evaporating black holes in 2D dilaton gravity, with a focus on a Bardeen-like regularized black hole model. I will discuss results from numerical simulations including the dynamics of the apparent horizons and additional trapped anti-trapped regions formed by backreaction.
