GW190521
Sign in to saveAlso known as S190521g, GW190521g
GW190521 (initially S190521g) 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 oth

GW190521 (initially S190521g) 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.
At 85 and 66 solar masses (M☉) respectively, the two black holes comprising this merger are the largest progenitor masses observed to date. The resulting black hole had a mass equivalent to 142 times that of the Sun, making this the first clear detection of an intermediate-mass black hole. The remaining 8 solar masses were radiated away as energy in the form of gravitational waves.
