Μελέτη της ικανότητας ανίχνευσης της διάχυτης ροής αστροφυσικών νετρίνο υψηλής ενέργειας με το τηλεσκόπιο KM3NeT/ARCA
Even though Cosmic Rays were discovered more than a century ago, the acceleration mechanisms of protons and heavier nuclei to ultra high energies still remain unknown. Being charged they are deflected by magnetic fields so they can not reveal the astrophysical objects responsible for their accelerat...
