December brings exciting news from the LIGO Scientific Collaboration and the Virgo Collaboration!
Four new black hole mergers have been officially announced – including GW170729, the largest and most distant GW source yet observed – and the full results of LIGO/Virgo’s first two observing runs have been organized and released in an official catalog. This catalog contains details on the ten binary black hole mergers and one binary neutron star merger that have been detected thus far.
More information can be found in the LSC Press Release, and the new catalog can be viewed here.
