Scalar waves in regular Bardeen black holes: Scattering, absorption and quasinormal modes (1605.00123v1)

Published 30 Apr 2016 in gr-qc

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-Nordstr\"om black holes, showing limiting cases for which their properties are similar.
