Simulation Study of Binary Mergers of Galaxy Clusters I: Properties of Merger Shocks and Radio Emission
Hyesung Kang, Dongsu Ryu, Jeongbhin Seo
We investigate binary mergers of galaxy clusters, the formation of shocks, and the resulting radio relics using three-dimensional simulations. The initial setup consists of two ide…

Energy Spectrum and Mass Composition of Ultra-High-Energy Cosmic Rays Originating from Relativistic Jets of Nearby Radio Galaxies
Jeongbhin Seo, Dongsu Ryu, Hyesung Kang
Relativistic jets of radio galaxies (RGs) are possible sources of ultra-high-energy cosmic rays (UHECRs). Recent studies combining relativistic hydrodynamic simulations with Monte…

Morphology and Mach Number Distribution of Merger Shock Surfaces in Merging Galaxy Clusters
Eunyu Lee, Dongsu Ryu, Hyesung Kang
In a binary merger of two subclusters with comparable masses, a pair of merger shocks are typically generated, often manifesting as double radio relics. Using cosmological hydrodyn…
