GWTC-3 Catalog Update

With the recent publication of the GWTC-3 catalog paper, some of the parameter estimation values that were previously published in our site have been updated to reflect those in the final publication.

GWTC-3 expands its predecessor GWTC-2.1 with 35 new compact binary coalescence candidates. Check out the GWTC-3 catalog page to browse the latest results.

We’ve released 16 additional channels from O3 !

Researchers at IAS made a request for some additional O3 data, and we’ve made these data available. The data release is intended to support studies of noise cleaning methods, and is available in frames with the tag AUX_CLN. It builds on a previous O3 auxiliary data release. We hope this will be useful for your research.

Learn more on the O3 Auxiliary Channel Data Release page.
