LIGO Detects Most Massive Black Hole Merger to Date
The LIGO-Virgo-KAGRA Collaboration has detected the most massive black hole merger to date, forming a final black hole around 225 times the Sun's mass. Caltech reports: Before now, the most massive black hole merger -- produced by an event that took place in 2021 called GW190521 -- had a total mass...
Caltech reports: Before now, the most massive black hole merger -- produced by an event that took place in 2021 called GW190521 -- had a total mass of 140 times that of the Sun. "The black holes appear to be spinning very rapidly -- near the limit allowed by Einstein's theory of general relativity," explains Charlie Hoy of the University of Portsmouth and a member of the LVK. "It will take years for the community to fully unravel this intricate signal pattern and all its implications," says Gregorio Carullo of the University of Birmingham and a member of the LVK.
