GW231123 ringdown: interpretation as multimodal Kerr signal
Harrison Siegel, Nicole M. Khusid, Maximiliano Isi +1
GW231123 is a short-duration, low-frequency gravitational wave signal consistent with a binary black hole coalescence and dominated by the merger-ringdown regime due to the high ma…
GW241011 and GW241110: Exploring Binary Formation and Fundamental Physics with Asymmetric, High-Spin Black Hole Coalescence
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1783
We report the observation of gravitational waves from two binary black hole coalescences during the fourth observing run of the LIGO--Virgo--KAGRA detector network, GW241011 and GW…
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,…
GW230814: investigation of a loud gravitational-wave signal observed with a single detector
The LIGO Scientific Collaboration, The Virgo Collaboration, The Kagra Collaboration +1783
GW230814, detected by the LIGO Livingston observatory with a signal-to-noise ratio of 42.4, represents the loudest gravitational-wave signal in the GWTC-4.0 catalog. Its source is…
Hiding Out at the Low End: No Gap and a Peak in the Black-Hole Mass Spectrum
Anarya Ray, Will Farr, Vicky Kalogera
In recent years, the existence of a gap in the mass spectrum of compact objects formed from stellar collapse, between the heaviest neutron stars and the lightest black holes, has b…
Identifying Compact Chirping SMBHBs in LSST using Bayesian Analysis
Chengcheng Xin, Maximiliano Isi, Will M. Farr +1
The Legacy Survey of Space and Time (LSST) is expected to observe up to million quasars in the next decade. In this work, we show that it is possible to use such data t…
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…
