[HEDS12-02] Particle acceleration by a relativistic shock propagating into an inhomogeneous medium

*Kanji Morikawa¹, Yutaka Ohira¹, Takumi Ohmura¹ (1. The University of Tokho)

Although a relativistic shock cannot accelerate particles efficiently, we found that the interaction between the shock and some upstream density fluctuations can make the downstream turbulent enough to accelerate the particles by the relativistic shock.
