Global Structure of the Nightside Proton Precipitation during Substorms using Simulations and Observations
… continued flux pileup. Using the OpenGGCM global MHD simulation, we show that the proton precipitation can be split azimuthally due to the arrested scattering in the strongly dipolarized region at the center of the SCW. However, at the edges of the SCW where the dipolarization is not as complete …

High resolution spectropolarimetric diagnostics of weak, small-scale magnetic fields in the solar photosphere
… three-dimensional radiative magnetohydrodynamic (MHD) simulation is used with SIR to produce synthetic observables in the same spectral window as observed by the GRIS-IFU. A parallelized wrapper to SIR is then used to perform nearly 14 million inversions of the synthetic spectra to test how well …

A Dynamic Coupled Magnetosphere-Ionosphere-Ring Current Model
… (LFM) global magnetohydrodynamics (MHD) simulation, the MIX ionosphere solver and the Rice Convection Model (RCM). We report some results of the coupled model using idealized inputs and model parameters. The algorithmic and physical components of the model are described, including …

Radiation asymmetry and MHD activity in rapid shutdowns on Alcator C-Mod
… the hot plasma core to the radiative edge by the MHD flow at one phase of an n = 1 global MHD mode. is phenomenology is confirmed by extended MHD simulation using the NIMROD code. An exponentially growing n = 1 magnetic mode is observed during the pre-TQ phase of MGI rapid shutdowns; the …

Cluster Weather Vanes: Radio Galaxies as Indicators of Galaxy Cluster Dynamics
… multiple three-dimensional magnetohydrodynamic (MHD) simulation studies focusing on the dynamics of Active Galactic Nuclei (AGN) jets. The goal of these studies is to understand the interactions of such jets with dynamical features of galaxy cluster media such as winds and shock waves, and to use …

Examining the growth and evolution of magnetic fields in clusters of galaxies: a numerical perspective
… large-scale cosmological magnetohydrodynamic (MHD) simulations of the formation of galaxy clusters including the seeding and growth of magnetic fields. Using large-scale cosmological simulations with the FLASH code combined with a simplified model of the acceleration of cosmic rays responsible …

Evolution of 3-d magnetic topology in flare-productive active regions
… behind solar flares based on observations, simulations and nonlinear force-free (NLFF) field modeling of magnetic fields. The data used in this study are obtained from several ground-based or space-borne instruments, including BBSO/DVMG, Hinode/SOT/SP, SDO/HMI and GOES. In addition, the …

Development of high energy pulsed plasma simulator for plasma-lithium trench experiment
… and a plasma heat flux of 0.42 GW/m2. Ideal MHD simulations are carried out to verify the experimental results on plasma transport. Ideal MHD and Athena MHD simulation code are found to be reasonable approximations to simulate behaviors of the plasma in the experimental condition. Simulation …
