The LIGO/Virgo/KAGRA collaboration has detected a gravitational wave signal, GW231123, from the most massive merger of two black holes. The resulting new black hole is 225 times more massive than the Sun. The detection is part of ongoing efforts to identify gravitational waves from black hole and neutron star mergers. LIGO employs laser interferometry, with detectors located in Washington and Louisiana, and is expanding with the KAGRA detector in Japan and future plans for LIGO-India. The collaboration has confirmed various merger events, including mixed mergers, enhancing the understanding of the mass gap in compact objects.
Physicists from the LIGO/Virgo/KAGRA collaboration announced the detection of gravitational wave signal GW231123 from the most massive merger of two black holes, creating a black hole 225 times the mass of the Sun.
The collaboration has successfully detected numerous merger events since its inception, including mixed mergers involving black holes and neutron stars, contributing significantly to our understanding of compact object physics.
