LIGO, Virgo and KAGRA complete the richest observation run to date

Today the international LIGO-Virgo-KAGRA Collaboration announces the completion of the fourth observation campaign (called O4) of the international network of gravitational wave detectors. Launched in May 2023, the campaign ends today after a period of coordinated...

LIGO, Virgo and KAGRA observed “second generation” black holes for the first time

A pair of very special black hole mergers, detected just one month apart in late 2024, is improving how scientists understand the nature and evolution of the most violent deep-space collisions in our universe. Some features of these mergers point toward the...

Hunting for continuous emission of gravitational waves from neutron stars

Hunting for continuous emission of gravitational waves from neutron stars

While Virgo and LIGO have been undergoing upgrades, the data from the early part of the third observing run of the detectors (from April to September, 2019), have been analysed by researchers to look for signs of continuous emission of gravitational waves from rapidly spinning neutron stars. This makes it possible to set new, clear constraints for future searches.
