Exceptional points and the breaking of Schwarzschild isospectrality under local potential perturbations
Mohamed Ould El Hadj
The odd- and even-parity gravitational perturbations of a Schwarzschild black hole are governed by the distinct Regge-Wheeler and Zerilli potentials, yet their quasinormal-mode (QN…
Scattering and conversion of electromagnetic and gravitational waves by Reissner-Nordström black holes: The Regge pole description
Mohamed Ould El Hadj
We investigate the problem of scattering and conversion of monochromatic planar gravitational and electromagnetic waves impinging upon a Reissner-Nordström black hole using a Regge…
Regge pole description of scattering by dirty black holes
Theo Torres, Mohamed Ould El Hadj, Shi-Qian Hu +1
We study the problem of plane monochromatic scalar waves impinging upon a Schwarzschild dirty black hole -- a Schwarzschild black hole surrounded by a thin spherical shell of matte…
Conversion of electromagnetic and gravitational waves by a charged black hole
Mohamed Ould El Hadj, Sam R. Dolan
In a strong electromagnetic field, gravitational waves are converted into electromagnetic waves of the same frequency, and vice versa. Here we calculate the scattering and conversi…
