LIGO-VIRGO-KAGRA (LVK) COLLABORATION DETECTED A REMARKABLE GRAVITATIONAL-WAVE SIGNAL
05 Apr 2024 — In May 2023, shortly after the start of the fourth LIGO-Virgo-KAGRA observing run, the LIGO Livingston detector observed a gravitational-wave signal from the collision of what is most likely a neutron star with a compact object that is 2.5 to 4.5 times the mass of our Sun. Neutron stars and black… Read More
