High-overtone ringdown fits: start time, no-hair tests, and correlations
Erin Coleman, Eliot Finch
Overtones are known to improve the performance of fits to the ringdown, both in numerical-relativity simulations and gravitational-wave observations. Although the overtone frequenc…
Black Hole Spectroscopy and Tests of General Relativity with GW250114
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration
The binary black hole signal GW250114, the loudest gravitational wave detected to date, offers a unique opportunity to test Einstein's general relativity (GR) in the high-velocity,…
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…
Statistical identification of ringdown modes with rational filters
Neil Lu, Sizheng Ma, Ornella J. Piccinni +2
Measuring quasinormal modes (QNMs) during the ringdown phase of binary black hole coalescences provides key insights into merger dynamics and enables tests of the no-hair theorem.…
Multimode ringdown modelling with and
Lorena Magaña Zertuche, Leda Gao, Eliot Finch +1
In the last decade, the ringdown community has made large strides in understanding the aftermath of binary black hole mergers through the study of numerical simulations. In this no…
