Abstract:
Cosmic rays are extremely energetic charged particles with energy up to 10^20 eV. Although these particles have been discovered for more than 100 years, the astrophysical sources of them are still unknown. As cosmic rays produce secondary neutrinos and gamma-rays within the source or during the propagation, neutrino and gamma-ray are important messengers to study the origin of the parent cosmic rays. In recent years, a lot of progress has been made in this area, thanks to IceCube, Fermi and IACT telescopes. I will discuss the multi-messenger approach, incorporating gamma-ray, neutrino and cosmic ray research, in studying the origin of Galactic and extra-Galactic cosmic rays.
