CVMFS Deprecation Notice
The CVMFS software tool to download gravitational-wave data locally in your machine will be discontinued and replaced by the Open Science Grid's Open Science Data Federation (OSDF) service. If you were using CVMFS before, read our new documentation page to learn how to make the switch to OSDF.
Open Data Workshop 2025
Registration is now open for the 2025 Open Data Workshop. This free workshop provides a crash-course in GW data analysis. You can participate online or in an in-person Study Hub. The workshop will be held May 12-14, 2025.


New API Version
Due to the growing number of event detections expected in the coming observing runs, we upgraded our GWOSC REST API to Version 2 to handle larger responses and high-frequency request demand. While the data content remains the same, the new version has reorganized its resources, and added pagination and throttling.
