Dynamical behavior of the -metric: charged scalar fields, quasinormal modes and superradiance
Kyriakos Destounis, Giacomo Mascher, Kostas D. Kokkotas
The -metric is a boost-symmetric spacetime solution to the vacuum Einstein field equations which describes black holes that are uniformly accelerated under the tension of a cosm…

Charged black holes in de Sitter space: superradiant amplification of charged scalar waves and resonant hyperradiation
Giacomo Mascher, Kyriakos Destounis, Kostas D. Kokkotas
Black holes typically inhabit highly dynamical galactic environments and are frequently permeated by accretion media. The inevitable scattering of scalar, electromagnetic and gravi…
