SANTOSTILO MASSIVE BLACK HOLE MERGER DETECTED, LARGEST YET VIA GRAVITATIONAL WAVES
Record-Setting Merger: GW231123 On 23 November 2023, during the fourth observing run, the LIGO–Virgo–KAGRA (LVK) network captured “GW231123,” a gravitational-wave signal from two merging black holes. One was about 100 M☉ (solar masses), the other around 140 M☉, and their union produced a behemoth of approximately 225 M☉, with the mass difference converting into energy released as spacetime … Read more
