Ruling out matter-induced bumps in black-hole effective potentials
Matteo Della Rocca, Romeo Felice Rosato, Paolo Pani
Matter fields localized around black holes can produce small secondary bumps in the effective potentials governing black-hole perturbations, potentially leading to quasinormal-mode…
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…
Extreme mass-ratio inspirals as probes of scalar fields: inclined circular orbits around Kerr black holes
Matteo Della Rocca, Susanna Barsanti, Leonardo Gualtieri +1
Extreme mass-ratio inspirals, a target source for the space-based gravitational wave detector LISA, are a sensitive probe of fundamental scalar fields coupled to gravity. We assess…
