Event List

GWTC-3-confident
Confident events from the O3b observing run for LIGO and Virgo, as described in the GWTC-3 catalog paper. These candidate events have a probability of astrophysical origin (probability of being a gravitational-wave signal versus being instrumental noise) assuming a compact binary (such as a binary black hole, neutron star-black hole binary or binary neutron star) coalescence source of greater than 0.5 based upon results of at least one of the search pipelines. These events are also included in a cumulative list of all GWTC events published to date. Details and additional data products are linked from the documentation page.
