Conformal transformation links black hole solutions to Rindler spacetime features.

Abstract

We study a two-dimensional dilaton gravity model related by a conformal transformation of the metric to the Callan-Giddings-Harvey-Strominger model. We find that most of the features and problems of the latter can be simply understood in terms of the classical and semiclassical dynamics of accelerated observers in two-dimensional Minkowski space.
