GWTC

The Gravitational-wave Transient Catalog (GWTC) is a cumulative set of gravitational wave transients maintained by the LIGO/Virgo/KAGRA collaboration. The online GWTC contains confidently-detected events from multiple data releases. For further information, see documentation for individual releases: GWTC-1, GWTC-2, GWTC-2.1, GWTC-3, and GWTC-4.0.

Note, this catalog is only updated periodically, and may not contain recently published events. For the most recent events, you can browse all available events.

Previous versions of this catalog are archived in zenodo or are available using the following links:
