Contributions to the Cosmic Ray Flux above the Ankle: Clusters of Galaxies
Hyesung Kang, Jörg P. Rachen, Peter L. Biermann
Motivated by the suggestion of Kang, Ryu \& Jones (1996) that particles can be accelerated to high energies via diffusive shock acceleration process at the accretion shocks formed…
Accreting Matter around Clusters of Galaxies: One-Dimensional Considerations
Dongsu Ryu, Hyesung Kang
During the formation of the large scale structure of the Universe, matter accretes onto high density peaks. Accreting collisionless dark matter (DM) forms caustics around them, whi…
Diffusive Shock Acceleration in Oblique MHD Shocks: Comparison with Monte Carlo Methods and Observations
Hyesung Kang, T. W. Jones
We report simulations of diffusive particle acceleration in oblique magnetohydrodynamical (MHD) shocks. These calculations are based on extension to oblique shocks of a numerical m…
Close Encounters between a Neutron Star and a Main-Sequence Star
Hyung Mok Lee, Sungsoo S. Kim, Hyesung Kang
We have examined consequences of strong tidal encounters between a neutron star and a normal star using SPH as a possible formation mechanism of isolated recycled pulsars in globul…
