Electron Preacceleration at Weak Quasi-perpendicular Intracluster Shocks: Effects of Preexisting Nonthermal Electrons

Ji-Hoon Ha, Dongsu Ryu, Hyesung Kang +1

Radio relics in the outskirts of galaxy clusters imply the diffusive shock acceleration (DSA) of electrons at merger-driven shocks with Mach number Ms​≲3−4 in the intrac…

Microinstabilities in the Transition Region of Weak Quasi-Perpendicular Intracluster Shocks

Sunjung Kim, Ji-Hoon Ha, Dongsu Ryu +1

Microinstabilities play important roles in both entropy generation and particle acceleration in collisionless shocks. Recent studies have suggested that in the transition zone of q…

Effects of Multi-scale Plasma Waves on Electron Preacceleration at Weak Quasi-perpendicular Intracluster Shocks

Ji-Hoon Ha, Sunjung Kim, Dongsu Ryu +1

Radio relics associated with merging galaxy clusters indicate the acceleration of relativistic electrons in merger-driven shocks with low sonic Mach numbers (Ms​≲3)…
