9th Korean Astrophysics Workshop (KAW9):

Proton Acceleration at Collisionless Shocks and

Gamma-ray Emission from Galaxy Clusters

July 10 - 12, 2017

CHEA, UNIST, Ulsan, Korea



Scientific Rationale

Cosmic-ray protons are expected to be accelerated at structure formation shocks. Inelastic collisions of shock-accelerated protons with ICM should produce pion0-decay gamma-ray, which could be detected by current gamma-ray telescopes. Then why do we not detect gamma-ray emission from galaxy clusters? This workshop aims to find answers to this important yet outstanding question.
