What 10 months of gravitational-wave data reveal about the cosmos

The LIGO Scientific collaboration, the Virgo collaboration, the KAGRA collaboration

May 26, 2026

The global network of gravitational-wave detectors—LIGO, Virgo, KAGRA, and GEO—released raw and processed data from April 2024 through January 2025, plus engineering runs beforehand. The open archive includes detector noise measurements, calibration details, and updated catalogs of candidate signals. Anyone can download and analyze the data.

Published as Open Data from LIGO, Virgo, and KAGRA through the Second Part of the Fourth Observing Run arXiv:2605.27090
