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 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 ()…
Electron Firehose Instabilities in High- ICM shocks
Sunjung Kim, Ji-Hoon Ha, Dongsu Ryu +1
The preacceleration of electrons through reflection and shock drift acceleration (SDA) is essential for the diffusive shock acceleration (DSA) of nonthermal electrons in collisionl…
