Numerical Analysis of Black Hole Evaporation in the CGHS Model

ORAL

Abstract

We numerically analyze the black hole formation and evaporation in the CGHS model, in the dynamical background of 1+1 dimensions. Specifically, we investigate the energy flux and the behavior of the asymptotic killing vector $\frac{\partial}{\partial y^-}$ at the future null infinity $\mathcal{I}_R^+$, and their relation to the rate of change of the Bondi mass of the black hole. Emphasis is given to the rapid evolution of the space-time near the point where the last ray reaches $\mathcal{I}_R^+$ and its implications about the information loss in this model.
