Gravitational waves in massive gravity: Waveforms generated by a particle plunging into a black hole and the excitation of quasinormal modes and quasibound states
Mohamed Ould El Hadj
With the aim of testing massive gravity in the context of black hole physics, we investigate the gravitational radiation emitted by a massive particle plunging into a Schwarzschild…

Electromagnetic radiation generated by a charged particle falling radially into a Schwarzschild black hole: A complex angular momentum description
Antoine Folacci, Mohamed Ould El Hadj
By using complex angular momentum techniques, we study the electromagnetic radiation generated by a charged particle falling radially from infinity into a Schwarzschild black hole.…

Scattering from compact objects: Regge poles and the complex angular momentum method
Mohamed Ould El Hadj, Tom Stratton, Sam R. Dolan
We calculate the Regge poles of the scattering matrix for a gravitating compact body, for scalar fields and for gravitational waves in the axial sector. For a neutron-starlike body…
