Schrödinger perturbation theory for black hole quasinormal modes
Jacopo Lestingi, Laura Sberna, Stephen R. Green
Deviations from vacuum general relativity (such as modified theories or the presence of an environment) produce small shifts in black hole quasinormal mode (QNM) spectra. These eff…
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)…
Waveform Modelling for the Laser Interferometer Space Antenna
LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…
Bilinear products and the orthogonality of quasinormal modes on hyperboloidal foliations
Marica Minucci, Rodrigo Panosso Macedo, Christiana Pantelidou +1
We explore the properties of bilinear products for black-hole quasinormal modes (QNMs) formulated on hyperboloidal foliations. We find that, although QNM solutions are smooth and f…
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…
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…
