Three-Dimensional Simulations of the Parker Instability in a Uniformly-rotating Disk
Jongsoo Kim, Dongsu Ryu, T. W. Jones
We investigate the nonlinear effects of uniform rotation on the Parker instability in an exponentially-stratified disk through high-resolution simulations. During the linear stage,…
Cosmic Rays and Their Radiative Processes in Numerical Cosmology
Dongsu Ryu, Francesco Miniati, Tom W. Jones +1
A cosmological hydrodynamic code is described, which includes a routine to compute cosmic ray acceleration and transport in a simplified way. The routine was designed to follow exp…
Gapped Phases of Quantum Wires
O. A. Starykh, D. L. Maslov, W. Häusler +1
We investigate possible nontrivial phases of a two-subband quantum wire. It is found that inter- and intra-subband interactions may drive the electron system of the wire into a gap…
Large Cosmic Shock Waves as Sites for Particle Acceleration
Francesco Miniati, Dongsu Ryu, Hyesung Kang +1
The properties of cosmic shock waves are studied through numerical simulations in two cosmological scenarios (SCDM and LCDM). The scaling relations for the average radius and veloc…
Ion injection and acceleration at modified shocks
U. D. J. Gieseler, T. W. Jones, Hyesung Kang
The theory of diffusive particle acceleration explains the spectral properties of the cosmic rays below energies of approx. 10^6 GeV as produced at strong shocks in supernova remna…
Monte-Carlo simulation of particle acceleration in braided magnetic fields
U. D. J. Gieseler, J. G. Kirk
Supernova remnants are expected to contain braided (or stochastic) magnetic fields, which are in some regions directed mainly perpendicular to the shock normal. For particle accele…
