Constraining deviations from the Teukolsky equation with GW250114
Sebastian H. Völkel, Nicola Franchini
The paper uses the GW250114 gravitational‑wave event to place the first theory‑agnostic limits on possible deviations from the Teukolsky equation, linking changes in the effective…

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 +70
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…
