GW231113_150041

Gravitational-wave source · GWTC-4.1

A black hole of about 82 solar masses, formed on 2023-11-13 when two black holes of roughly 56 and 29 solar masses spiralled together 17.0 billion light-years away. LIGO and Virgo felt the collision as ripples in spacetime.

the two that merged

The two black holes that merged were about 56 (34–94) and 29 (13–47) solar masses. The remnant is 82 (57–126) solar masses. Values in parentheses are the 90% credible ranges from LIGO, Virgo and KAGRA (GWTC).

Its event horizon, the edge past which nothing returns, spans about 242 km in radius. The waves we detected had been travelling for 17.0 billion years before they reached us.
