KM3NeT real-time analysis framework
KM3NeT is a deep-sea neutrino observatory under construction at two sites in the Mediterranean
Sea. The ARCA telescope (Italy), aims at identifying and studying TeV-PeV astrophysical neutrino
sources, while the ORCA telescope (France), aims at studying the intrinsic properties of neutrinos
in the few-GeV range. Since they are optimised in complementary energy ranges, both telescopes
can be used to do neutrino astronomy from a few MeV to a few PeV, despite of their different pri-
mary goals. The KM3NeT observatory takes active part to the real-time multi-messenger searches,
which allow to study transient phenomena by combining information from the simultaneous ob-
servation of complementary cosmic messengers with different observatories. In this respect, a key
component is the real-time distribution of alerts when potentially interesting detections occur, in
order to increase the discovery potential of transient sources and refine the localization of poorly
localized triggers, such as gravitational waves. The KM3NeT real-time analysis framework is
currently reconstructing all ARCA and ORCA events, searching for spatial and temporal coin-
cidences with alerts received from other operating multi-messenger instruments and performing
core-collapse supernova analyses. The selection of a sample of interesting events to send alerts
to the external multi-messenger community is presently under definition. This contribution deals
with the status of the KM3NeT real-time analysis framework and its first results
