The Third Open Gravitational-wave Catalog of Compact-binary Coalescences

3-OGC: Catalog of gravitational waves from compact-binary mergers

This consists of 55 binary black hole mergers and the two binary neutron star mergers gw170817 and gw190425.We estimate the parameters of all binary black hole events using an up-to-date waveform model that includes both sub-dominant harmonics and precession effects.We find no significant binary neutron star or neutron star--black hole merger events.
