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, and GWTC-3.

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.

  • Toggle columns on/off with Display button at right.
  • Click an event name for all versions and more information.
  • Values in the table below are from the Default SEARCH and Default PE cases found in the individual event's page.
  • See Event Portal Usage Notes for more details.
List contains 93 events.
