GWTC-3: Compact Binary Coalescences Observed by LIGO and Virgo During the Second Half of the Third Observing Run

On May 21, 2019 the LIGO/Virgo interferometers detected GW190521, the most massive gravitational wave binary observed to date. The two component 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.

GW150914 is the first gravitational wave signal ever detected and the first discovery of a binary of black holes, marking the beginning of Gravitational astronomy. This discovery was made by the “online” low-latency version of coherent WaveBurst: the original screenshot of GW150914 event can be found here.

This is a copy of the original CED which triggered the attention of all the LIGO/Virgo Collaboration due to its strength and chirping morphology.
