Description
During its fourth observing run (O4), the LIGO–Virgo–KAGRA Collaboration reported hundreds of gravitational-wave events. In this talk, I will summarize the gravitational-wave alerts issued during O4 and the multi-messenger follow-up observations they triggered. Despite extensive follow-up observations, no electromagnetic counterpart has so far been identified. I will then discuss what can nonetheless be learned from the O4 events from a multi-messenger perspective. Finally, I will present the future prospects for gravitational-wave alerts and multi-messenger astronomy in the upcoming Intermediate Run (IR1) and in O5.
