Acceleration of Cosmic Ray Electrons at Weak Shocks in Galaxy Clusters
Hyesung Kang, Dongsu Ryu, T. W. Jones
According to structure formation simulations, weak shocks with typical Mach number, , are expected to form in merging galaxy clusters. The presence of such sho…
Particle Acceleration at Structure Formation Shocks
Hyesung Kang
Cosmological hydrodynamic simulations have demonstrated that shock waves could be produced in the intergalactic medium by supersonic flow motions during the course of hierarchical…
Shock Acceleration Model with Postshock Turbulence for Giant Radio Relics
Hyesung Kang
We explore the shock acceleration model for giant radio relics, in which relativistic electrons are accelerated via diffusive shock acceleration (DSA) by merger-driven shocks in th…
Properties of Merger Shocks in Merging Galaxy Clusters
Ji-Hoon Ha, Dongsu Ryu, Hyesung Kang
X-ray shocks and radio relics detected in the cluster outskirts are commonly interpreted as shocks induced by mergers of sub-clumps. We study the properties of merger shocks in mer…
Shock Acceleration Model for the Toothbrush Radio Relic
Hyesung Kang, Dongsu Ryu, T. W. Jones
Although many of the observed properties of giant radio relics detected in the outskirts of galaxy clusters can be explained by relativistic electrons accelerated at merger-driven…
The Case for Electron Re-Acceleration at Galaxy Cluster Shocks
Reinout J. van Weeren, Felipe Andrade-Santos, William A. Dawson +16
On the largest scales, the Universe consists of voids and filaments making up the cosmic web. Galaxy clusters are located at the knots in this web, at the intersection of filaments…
