High-energy neutrino astronomy

Abstract

Neutrinos constitute a unique probe since they escape from their sources, travel undisturbed on cosmological distances and are produced in high-energy (HE) hadronic processes. In particular they would allow a direct detection and unambiguous identification of the acceleration sites of HE baryonic cosmic rays (CR), which remain unknown. The latest results achieved with the current experiments are briefly reviewed, including the efforts towards a multi-messenger approach. © Author(s) 2011.
