GWTC-4.0
Confident events from the O4a observing run for LIGO and Virgo, as described in the GWTC-4.0 catalog paper. For details of all events in the cumulative GWTC-4.0 catalog, see GWTC catalog. 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 or a false alarm rate of less than 1 per year based upon results of at least one of the search pipelines. Details and additional data products are linked from the documentation page.
