Gravitational wave detectors complete two year campaign with record signal count



Berlin, Germany (SPX) Nov 19, 2025
The LIGO, Virgo, and KAGRA collaborations have finished their fourth observation campaign, known as O4, marking the longest and most comprehensive period of coordinated gravitational wave monitoring to date. Initiated in May 2023 and spanning more than two years, the campaign involved simultaneous data analysis and resulted in the detection of 250 new gravitational signals, which account for more than two-thirds of all signals recorded by these observatories to date. Improvements in detector techn ... read more
