The LIGO Scientific Collaboration and the Virgo Collaboration announced the discovery of GW190521, the most massive gravitational wave binary observed to date. The two inspiralling black holes had masses of about 85 and 66 solar masses, and resulted in the formation of a black hole remnant of 142 solar masses. This remnant provides the first clear detection of an “intermediate-mass” black hole.
