Descripción
KM3NeT, a deep-sea Cherenkov neutrino telescope with MeV–PeV sensitivity, comprises two detectors: ARCA (high-energy astrophysical neutrinos) and ORCA (low-energy oscillations/atmospheric studies). With roughly 25% of the detectors deployed, it is partially operational, and the full completion is expected by the end of the decade.
Its design provides a large field of view including the galactic center, a high duty cycle, an angular resolution as low as 0.1º above 100 TeV and a sensitivity to energies from MeV to PeV. These features enable it to address diverse physics goals, including the search for astrophysical neutrino sources or the detection of very high-energy neutrinos.
In the era of time-domain and multi-messenger astronomy, rapid sharing of transient observations is critical. KM3NeT’s capabilities, coupled to an online analysis pipeline make it a key asset for identifying neutrino candidates and triggering follow-up.
This contribution describes KM3NeT’s Alert System, covering the Architecture allowing for a low-latency data processing and event reconstruction; the Selection criteria used for background suppression and candidate prioritization, and the Alert protocol describing the dissemination thresholds and strategy. We highlight the system’s role in enabling prompt follow-up of neutrino transients within the global multi-messenger network.
