Scalar waves in regular Bardeen black holes: Scattering, absorption and quasinormal modes

Abstract

We discuss the phenomenology of massless scalar fields around a regular Bardeen black hole, namely absorption cross section, scattering cross section and quasinormal modes. We compare the Bardeen and Reissner-Nordström black holes, showing limiting cases for which their properties are similar.
