GW190814 è un segnale di onde gravitazionali individuato nell'agosto 2019 dagli interferometri VIRGO e LIGO. GW190814 est un signal d'onde gravitationnelle observé par les détecteurs LIGO et Virgo le 14 août 2019 à 21:10:39 UTC, et ayant un rapport signal sur bruit de 25 dans le réseau des trois détecteurs. Le signal était associé au super-événement astronomique S190814bv, situé à 790 millions d'années-lumière, soit 241 mégaparsecs, dans la zone de localisation 18,5 deg2 vers la Baleine ou le Sculpteur. Aucune contrepartie optique n'a été découverte malgré une recherche approfondie dans la région de probabilité. GW 190814 was a gravitational wave (GW) signal observed by the LIGO and Virgo detectors on 14 August 2019 at 21:10:39 UTC, and having a signal-to-noise ratio of 25 in the three-detector network. The signal was associated with the astronomical superevent S190814bv, located 790 million light years away, in location area 18.5 deg2 towards Cetus or Sculptor. No optical counterpart was discovered despite an extensive search of the probability region.
