Scalar absorption by charged rotating black holes
arXiv:1708.03370 · doi:10.1103/PhysRevD.96.044043
Abstract
We compute numerically the absorption cross section of planar massless scalar waves impinging upon a Kerr-Newman black hole with different incidence angles. We investigate the influence of the black hole electric charge and angular momentum in the absorption spectrum, comparing our numerical computations with analytical results for the limits of high and low frequency.
