High-energy neutrino and gamma-ray connections of cosmic-ray sources

Recent progress of cosmic particle observations has deepened our knowledge on the non-thermal Universe. New data on high-energy cosmic rays, gamma rays, and neutrinos are now available thanks to various experiments, and multi-messenger approaches give us powerful clues to the mysteries about the origins of high-energy cosmic neutrinos and cosmic rays. In this talk, we discuss physical connections among multi-messenger particles and consider their implications. In particular, in view of the latest IceCube data in the 10-100 TeV range, we emphasize the relevance of all-sky or targeted searches for keV-GeV electromagnetic counterparts of the neutrino sources.
