How can you learn in real-time about new gravitational-wave candidate signals discovered by @LIGO, Virgo, and KAGRA during the fourth observing run O4? One possibility: the “Public Alerts” on the GraceDB webpage:

GraceDB | The Gravitational-Wave Candidate Event Database

@mpi_grav @LIGO

You can also download the Astro-COLIBRI app (iOS or Android) and switch on the various realtime notifications. Incl. several streams dedicated to GWs. Once you see an interesting event, the direct link to the full information in GraceDB (and plenty of other ressources) is right there as well...

Have fun!
