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…
Waveforms in massive gravity and neutralization of giant black hole ringings
Yves Décanini, Antoine Folacci, Mohamed Ould El Hadj
A distorted black hole radiates gravitational waves in order to settle down in a smoother geometry. During that relaxation phase, a characteristic damped ringing is generated. It c…
Waveforms produced by a scalar point particle plunging into a Schwarzschild black hole: Excitation of quasinormal modes and quasibound states
Yves Decanini, Antoine Folacci, Mohamed Ould El Hadj
With the possibility of testing massive gravity in the context of black hole physics in mind, we consider the radiation produced by a particle plunging from slightly below the inne…
Resonant excitation of black holes by massive bosonic fields and giant ringings
Yves Decanini, Antoine Folacci, Mohamed Ould El Hadj
We consider the massive scalar field, the Proca field and the Fierz-Pauli field in the Schwarzschild spacetime and we focus more particularly on their long-lived quasinormal modes.…
Giant black hole ringings induced by massive gravity
Yves Decanini, Antoine Folacci, Mohamed Ould El Hadj
A distorted black hole radiates gravitational waves in order to settle down in one of the geometries permitted by the no-hair theorem. During that relaxation phase, a characteristi…
