A set of dedicated studies on KM3-230213A
20 February 2025 – Recently the KM3NeT Collaboration has published evidence for the cosmic neutrino with the highest energy ever detected (the article on Nature can be accessed from here). This event is identified as KM3-230213A.
In a set of dedicated studies, the Collaboration has investigated the possible sources of the event and the implications that may be derived from it.
