Gravitational electric-magnetic duality at the light ring and quasinormal mode isospectrality in effective field theories
Ibrahima Bah, Emanuele Berti, Valerio De Luca +2
Black hole perturbations are characterized by a superposition of damped exponentials known as quasinormal modes. In general relativity, the spectra of parity-even and parity-odd qu…
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 quasinormal mode resonances
Yiqiu Yang, Emanuele Berti, Nicola Franchini
Black hole quasinormal mode frequencies can be very close to each other ("avoided crossings") or even completely degenerate ("exceptional points") when the system is characterized…
Fast and accurate parameter estimation of high-redshift sources with the Einstein Telescope
Filippo Santoliquido, Jacopo Tissino, Ulyana Dupletsa +9
The Einstein Telescope (ET), along with other third-generation gravitational wave (GW) detectors, will be a key instrument for detecting GWs in the coming decades. However, analyzi…
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…
