Constraining deviations from the Teukolsky equation with GW250114
Sebastian H. Völkel, Nicola Franchini
The recent gravitational-wave detection GW250114 by the LIGO-Virgo-KAGRA (LVK) Collaboration provides unprecedented precision for testing general relativity (GR) through black hole…
Quasinormal modes of rotating black holes beyond general relativity in the WKB approximation
Ruijing Tang, Nicola Franchini, Sebastian H. Völkel +1
Exploring gravitational theories beyond general relativity (GR) with black hole (BH) spectroscopy requires accurate and flexible methods for computing their quasinormal mode (QNM)…
Black hole spectroscopy: from theory to experiment
Emanuele Berti, Vitor Cardoso, Gregorio Carullo +65
The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes a…
Hyperbolicity in scalar-Gauss-Bonnet gravity: a gauge invariant study for spherical evolution
Farid Thaalba, Nicola Franchini, Miguel Bezares +1
We study spherical evolution in scalar-Gauss-Bonnet gravity with additional Ricci coupling and use the gauge-invariant approach of Ref.~\cite{Reall:2021voz} to track well-posedness…
The dynamics of spherically symmetric black holes in scalar-Gauss-Bonnet gravity with a Ricci coupling
Farid Thaalba, Nicola Franchini, Miguel Bezares +1
We study the dynamics of spherically symmetric black holes in scalar Gauss-Bonnet gravity with an additional coupling between the scalar field and the Ricci scalar using non-linear…
Higher-derivative corrections to the Kerr quasinormal mode spectrum
Pablo A. Cano, Lodovico Capuano, Nicola Franchini +2
We provide the most complete analysis so far of quasinormal modes of rotating black holes in a general higher-derivative extension of Einstein's theory. By finding the corrections…
