Potential science with GW250114 -- the loudest binary black hole merger detected to date
Aleyna Akyüz, Alex Correia, Jada Garofalo +7
On January 14, 2025 the LIGO interferometers detected a gravitational wave from the merger of two black holes, GW250114. Using publicly available information, we estimate that the…
Mining the Alerts: A Preliminary Catalog of Compact Binaries from the Fourth Observing Run
Aleyna Akyüz, Alex Correia, Jada Garofalo +7
We present a preliminary catalog of compact binary merger candidates from the ongoing fourth observing run (O4) of Advanced LIGO, Virgo, and KAGRA, based on an analysis of public a…
Low evidence for ringdown overtone in GW150914 when marginalizing over time and sky location uncertainty
Alex Correia, Yi-Fan Wang, Julian Westerweck +1
Tests of the no-hair theorem using astrophysical black holes involve the detection of at least two quasi-normal modes (QNMs) in the gravitational wave emitted by a perturbed black…
Sky marginalization in black hole spectroscopy and tests of the area theorem
Alex Correia, Collin D. Capano
Direct observation of gravitational waves from binary black hole (BBH) mergers has made it possible to test the laws of black hole thermodynamics using real astrophysical sources.…
