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…
A Simulation Study of Low-Power Relativistic Jets: Flow Dynamics and Radio Morphology of FR-I Jets
Ayan Bhattacharjee, Jeongbhin Seo, Dongsu Ryu +1
Radio galaxies are classified into two primary categories based on their morphology: center-brightened FR-I and edge-brightened FR-II. It is believed that the jet power and interac…
Model Spectrum of Ultra-High-Energy Cosmic Rays Accelerated in FR-I Radio Galaxy Jets
Jeongbhin Seo, Dongsu Ryu, Hyesung Kang
Nearby radio galaxies (RGs) of Fanaroff-Riley Class I (FR-I) are considered possible sites for the production of observed ultra-high-energy cosmic rays (UHECRs). Among those, some…
HOW-MHD: A High-Order WENO-Based Magnetohydrodynamic Code with a High-Order Constrained Transport Algorithm for Astrophysical Applications
Jeongbhin Seo, Dongsu Ryu
Due to the prevalence of magnetic fields in astrophysical environments, magnetohydrodynamic (MHD) simulation has become a basic tool for studying astrophysical fluid dynamics. To f…
A Simulation Study of Ultra-relativistic Jets -- III. Particle Acceleration at FR-II Jets
Jeongbhin Seo, Dongsu Ryu, Hyesung Kang
We study the acceleration of ultra-high-energy cosmic rays (UHECRs) at FR-II radio galaxies by performing Monte Carlo simulations for the transport, scattering, and energy change o…
A Simulation Study of Ultra-relativistic Jets -- II. Structures and Dynamics of FR-II Jets
Jeongbhin Seo, Hyesung Kang, Dongsu Ryu
We study the structures of ultra-relativistic jets injected into the intracluster medium (ICM) and the associated flow dynamics, such as shocks, velocity shear, and turbulence, thr…
A Simulation Study of Ultra-Relativistic Jets -- I. A New Code for Relativistic Hydrodynamics
Jeongbhin Seo, Hyesung Kang, Dongsu Ryu +2
In an attempt to investigate the structures of ultra-relativistic jets injected into the intracluster medium (ICM) and the associated flow dynamics, such as shocks, velocity shear,…
The Contribution of Stellar Winds to Cosmic Ray Production
Jeongbhin Seo, Hyesung Kang, Dongsu Ryu
Massive stars blow powerful stellar winds throughout their evolutionary stages from the main sequence to Wolf-Rayet phases. The amount of mechanical energy deposited in the interst…
