Study of the all-sky diffuse astrophysical neutrino flux and of the Galactic ridge with KM3NeT/ARCA data

The KM3NeT Collaboration is building and deploying two deep-sea Cherenkov detectors in the Mediterranean Sea. The primary goal of the KM3NeT/ARCA detector is neutrino astronomy in the TeV-PeV range, while the KM3NeT/ORCA detector is optimized for atmospheric neutrino oscillations studies at energies of a few GeV. When completed,
