Not Their First Rodeo: Gravitational Wave Detectors Spot Merging Black Holes That Have Merged Before
The gravitational wave events GW241011 and GW241110 provide strong evidence for the growth of black holes through successive mergers.

Our fourth observing run (O4) has seen our detectors perform better than ever before. Together with @egovirgo.bsky.social and KAGRA we have identified more gravitational-wave candidates than in all previous observing runs combined

O4 was a success thanks to lots of hard work from across the world.

LIGO, Virgo and KAGRA constantly battle with quantum effects on their mirrors (objects weighing more than 40 kg!), such as quantum radiation pressure noise, that is, fluctuations of the laser field that causes the mirrors to jitter.
