Our #Introduction: We are an international collaboration of scientists working to detect and study #GravitationalWaves

We made our first observation in 2015, and working with our colleagues in Virgo and KAGRA, have now produced a catalog of gravitational waves from the coalescence of black hole and neutron star binaries

We're currently in our fourth observing run, which features frequent new discoveries

We're happy to join Mastodon for some #SciComm

Data (with some filtering) from our first observation of gravitational waves: GW150914. The data from the two LIGO sites (Livingston and Hanford) show the same signal, which gave us confidence that it was a real gravitational waves. The signal come from the coalescence of two black holes

Our current observing plan. Our current observing run (O4) is due to contniue until Novermber 2025. We are joined by Virgo and KAGRA for the current observations. The future timeline is currently uncertain, but we'll provide updates when we can.

Estimates for the masses of the black holes and neutron stars that produced the gravitational waves in our most recent catalog, GWTC-3. There is getting to be rather a lot of them, but there will be many more soon!
