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)…
Green function of the Pöschl-Teller potential
Adrien Kuntz
We use an approximation of the Regge-Wheeler-Zerilli potential, known as Pöschl-Teller, to exactly compute the time-domain Green function of black hole perturbations in this simpl…
Black hole spectroscopy: from theory to experiment
Emanuele Berti, Vitor Cardoso, Gregorio Carullo +70
The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes a…
Ringdown nonlinearities in the eikonal regime
Bruno Bucciotti, Vitor Cardoso, Adrien Kuntz +2
The eikonal limit of black hole quasinormal modes (the large multipole limit ) can be realized geometrically as a next-to-leading order solution to the geometric optics…
Amplitudes and Polarizations of Quadratic Quasi-Normal Modes for a Schwarzschild Black Hole
Bruno Bucciotti, Leonardo Juliano, Adrien Kuntz +1
General Relativity predicts the existence of quadratic quasi-normal modes at second order in perturbation theory. Building on our recent work, we compute the amplitudes and polariz…
