Abstract
Cosmic rays (CRs) are charged subatomic particles from outside of the Earth with energies up to 1020 eV. It is still unknown for the origin of these high-energy particles. The secondary gamma-rays and neutrinos can be produced by cosmic rays within the accelerated sources or on the way of propagation, which are important messengers to search for the original accelerators of cosmic rays. In recent years, the multi-messenger study of cosmic ray has made great progress thanks to the observations from Fermi satellite, the atmospheric Cherenkov telescopes, and the IceCube neutrino detector. I will introduce these progresses and discuss the possible research topics in the future.
