Revisiting environmental effects on black hole quasibound-state spectra with relativistic perturbation theory
Yin-Da Guo, Qi-Xuan Xu, Richard Brito +1
We present a relativistic framework for computing corrections to the eigenfrequency spectrum of a massive scalar field in perturbed black-hole spacetimes, including first-order shi…
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)…
Post-Minkowskian expansion of the Prompt Response in a Schwarzschild background
Marina De Amicis, Enrico Cannizzaro
We study the early-time component of the Green's function of a Schwarzschild black hole, traveling on the curved light cone and usually denoted as the prompt response. Working in a…
Excitation of scalar quasi-normal modes from boson clouds
Enrico Cannizzaro, Marco Palleschi, Laura Sberna +2
Massive scalar fields on black hole backgrounds generally admit two families of modes: quasi-bound states (QBS) and quasinormal modes (QNM). We demonstrate the orthogonality betwee…
Dynamical quasinormal mode excitation
Marina De Amicis, Enrico Cannizzaro, Gregorio Carullo +1
We study the dynamical excitation of quasinormal modes (QNMs) through the plunge, merger and ringdown of an extreme-mass-ratio-inspiral into a Schwarzschild black hole, for generic…
Impact of a plasma on the relaxation of black holes
Enrico Cannizzaro, Thomas F. M. Spieksma, Vitor Cardoso +1
Our universe is permeated with interstellar plasma, which prevents propagation of low-frequency electromagnetic waves. Here, we show that two dramatic consequences arise out of suc…
