Abstract: The recent discovery of high-energy astrophysical neutrinos has opened a new window to the Universe. However, the sources of those neutrinos are still unknown. Among the plausible candidates are active galactic nuclei, gamma-ray bursts and supernovae. Combining neutrino data with electromagnetic measurements in a multi-messenger approach will increase the sensitivity to identify the neutrino sources and help to solve long-standing problems in astrophysics such as the origin of cosmic rays.
I will review the recent progress in multi-messenger astronomy using neutrino data.
