Abstract

Read online

KM3NeT is a Cherenkov-light based neutrino telescope located in the Mediterranean Sea, comprising two detectors ARCA (Sicily, It) and ORCA (Var, Fr). Currently at ∼15% of its total deployment, with completion expected by 2029, it has an energy sensitivity ranging from MeV to PeV. The infrastructure is well suited to detect astrophysical neutrinos thanks to a wide field of view and high duty cycle. In the context of multi-messenger astronomy, KM3NeT aims at quickly reconstructing data to identify neutrino candidates, both to search for coincidences after external triggering and to send alerts. This contribution reports on the online analysis framework status, allowing follow-up of alerts from partner experiments and operational since late 2022.
