Description

KM3NeT is a large research infrastructure that will consist of a network of deep-sea neutrino telescopes in the Mediterranean Sea, of which the ARCA detector installed in the CapoPassero site (Italy) is optimised for studying high-energy neutrinos of cosmic origin. Thanks to its geographical location on the Northern hemisphere, KM3NeT can observe most of the Galactic Plane, including the galactic centre. Prime targets of KM3NeT/ARCA are therefore neutrino sources in our Galaxy. While extragalactic candidate neutrino sources are numerous, the estimates of their neutrino fluxes have large uncertainties due to model assumptions and to the intergalactic absorption of VHE gamma-rays that strongly modifies the gamma-ray spectra measured at Earth. On the other hand, under the hypothesis of hadronic gamma emission and transparent sources, models for galactic neutrino sources are well constrained by TeV gamma-ray observations and allow to obtain realistic expectations on the detection perspectives. We report the ARCA sensitivities for galactic sources such as the supernova remnant RXJ1713.7-3946 and the pulsar wind nebula Vela Jr, and also the discovery potential for generic point sources with an $E^{-2}$ spectrum. Analysis methods and results will be presented both for the track and cascade channels.
