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…
Adiabatic evolution of asymmetric binaries on generic orbits with new fundamental fields I: characterization of gravitational wave fluxes
Sara Gliorio, Matteo Della Rocca, Susanna Barsanti +3
We investigate the dynamics of asymmetric binaries in extensions of General Relativity featuring a massless scalar field non-minimally coupled to gravity, focusing on the interplay…
Quasinormal ringing of Kerr black holes. III. Excitation coefficients for equatorial inspirals from the innermost stable circular orbit
Matteo Della Rocca, Laura Pezzella, Emanuele Berti +2
The remnant of a black hole binary merger settles into a stationary configuration by "ringing down" through the emission of gravitational waves that consist of a superposition of d…
Gravitational Atom Spectroscopy
Matteo Della Rocca, Thomas F. M. Spieksma, Francisco Duque +2
Black holes in our Universe are rarely truly isolated, being instead embedded in astrophysical environments such as plasma or dark matter. A particularly intriguing possibility is…
Probing time-dependent scalar wigs with extreme mass ratio inspirals
Matteo Della Rocca, Georgios Antoniou, Leonardo Gualtieri +1
We investigate the gravitational wave emission from extreme mass ratio inspirals, key targets for the upcoming space-based detector LISA, considering the scenario where the lighter…
