Supersonic Collisions between Two Gas Streams
Hyung Mok Lee, Hyesung Kang, Dongsu Ryu
A star around a massive black hole can be disrupted tidally by the gravity of the black hole. Then, its debris may form a precessing stream which may even collide with itself. In o…
Cluster Accretion Shocks as Possible Acceleration Sites for Ultra High Energy Protons below the Greisen Cutoff
Hyesung Kang, Dongsu Ryu, T. W. Jones
Three-dimensional hydrodynamic simulations of large scale structure in the Universe have shown that accretion shocks form during the gravitational collapse of one-dimensional caust…
Background X-ray Emission from Hot Gas in CDM and CDM+Lambda Universes: Spectral Signatures
Renyue Cen, Hyesung Kang, Jeremiah P. Ostriker +1
We present a new treatment of two popular models for the growth of structure, examining the X-ray emission from hot gas with allowance for spectral line emission from various atomi…
Diffusive Shock Acceleration Simulations: Comparison with Particle Methods and Bow Shock Measurements
Hyesung Kang, T. W. Jones
Direct comparisons of diffusive particle acceleration numerical simulations have been made against Monte Carlo and hybrid plasma simulations by Ellison {\it et. al.} (1993) and aga…
