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:
- 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 219 events.
