LIGO-Virgo-KAGRA detect most massive black hole merger to date
The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed with gravitational waves, using the US National Science Foundation-funded (NSF) LIGO Hanford and Livingston Observatories. The merger produced a final black hole more than 225 times the mass of our Sun. The signal, designated GW231123, was observed during the… Read More
