Excitation factors and exceptional points of Kerr-de Sitter quasinormal modes
Dario Rossi, Naritaka Oshita, Leonardo Gualtieri +1
We compute the excitation factors of Kerr-de Sitter black hole quasinormal modes using two different techniques: a Heun function representation and an expansion of the solution in…
Dynamical tidal response of neutron stars: From effective field theory to gravitational waveforms
Thomas Apostolidis, Valerio De Luca, Leonardo Gualtieri +3
We investigate the fully relativistic dynamical tidal response of neutron stars up to second order in the frequency. Combining the worldline effective field theory for extended gra…
Minimum mass, maximum charge and hyperbolicity in scalar Gauss-Bonnet gravity
Dario Rossi, Leonardo Gualtieri, Thomas P. Sotiriou
We study the loss of hyperbolicity of perturbation equations for black hole solutions of scalar Gauss-Bonnet gravity. We consider a class of coupling functions allowing for static…
Nonperturbative suppression of beyond-General-Relativity effects in quadratic gravity
Georgios Antoniou, Leonardo Gualtieri, Paolo Pani
Quadratic gravity is a well-motivated extension of general relativity~(GR) wherein the Einstein-Hilbert action is augmented by quadratic curvature terms. This theory is equivalent…
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…
