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…
The First Magnetic Fields
George Davies, Lawrence M. Widrow
We demonstrate that the Biermann battery mechanism for the creation of large scale magnetic fields can arise in a simple model protogalaxy. Analytic calculations and numerical simu…
Enhanced Cloud Disruption by Magnetic Field Interaction
G. Gregori, Francesco Miniati, Dongsu Ryu +1
We present results from the first three-dimensional numerical simulations of moderately supersonic cloud motion through a tenuous, magnetized medium. We show that the interaction o…
The MHD Kelvin-Helmholtz Instability III: The Role of Sheared Magnetic Field in Planar Flows
Hyunju Jeong, Dongsu Ryu, T. W. Jones +1
We have carried out simulations of the nonlinear evolution of the magnetohydrodynamic (MHD) Kelvin-Helmholtz (KH) instability for compressible fluids in -dimensions,…
Simulations of Nonthermal Electron Transport in Multidimensional Flows: Synthetic Observations of Radio Galaxies
I. L. Tregillis, T. W. Jones, Dongsu Ryu +1
We have applied an effective numerical scheme for cosmic-ray transport to 3D MHD simulations of jet flow in radio galaxies (see the companion paper by Jones et al. 1999). The marri…
