GW190521
Gravitational-wave observation
Summary
GW190521 was a gravitational wave signal resulting from the merger of two black holes. It was possibly associated with a coincident flash of light; if this association is correct, the merger would have occurred near a third supermassive black hole. The event was observed by the LIGO and Virgo detectors on 21 May 2019 at 03:02:29 UTC, and published on 2 September 2020. The event had a Luminosity distance of 17 billion light years away from Earth, within a 765 deg2 area towards one of two roughly antipodal areas of the sky, one centered around Coma Berenices and the other in Tucana.
