GW190814

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 super event S190814bv, located 790 million light years away, in location area 18.5 deg2 towards Sculptor. No optical counterpart was discovered despite an extensive search of the probability region.

In June 2020, astronomers reported details of a compact binary merging, in the "mass gap" of cosmic collisions, of a first-ever "mystery object", either an extremely heavy neutron star (that was theorized not to exist) or a too-light black hole, with a black hole, that was detected as the gravitational wave GW190814.
