Spectral instabilities in the time domain
Taillte May, Adrien Kuntz, Nicola Franchini +2
We investigate the effect of a spectral instability on the time domain waveform using a one-dimensional double Pöschl-Teller model. By analytically following successive scatterings…
Second-order scattering response of a Schwarzschild black hole
Bruno Bucciotti, Jaime Redondo-Yuste, Adrien Kuntz +2
Gravitational waves couple in a nonlinear fashion in the vicinity of a black hole. Black hole perturbation theory can be readily applied to compute the magnitude of this coupling,…
Vanishing of all redshift modes in Schwarzschild ringdown
Adrien Kuntz, Matteo Della Rocca
Several studies of black hole ringdown from particles plunging into black holes have identified contributions decaying at integer multiples of the surface gravity, called redshift…
Dynamical quasinormal mode excitation II: propagation and convergence in Schwarzschild
Marina De Amicis, Enrico Cannizzaro, Gregorio Carullo +2
We study the dynamical excitation of quasinormal modes (QNMs) during the plunge of a particle into a Schwarzschild black hole, building on the framework of Phys. Rev. D 113 (2026)…
