GWgraph17

When black holes merge, they form even more massive black holes. The first two mergers observed by the LIGO Scientific Consortium, GW150914 and GW151226, yielded black holes with 62 and 21 solar masses, respectively. The most recent detection, GW170104, produced a black hole with about 49 solar masses. Graphic courtesy LSC/Sonoma State University/Aurore Simonnet
