RADIATIVE MAGNETOHYDRODYNAMIC SIMULATION OF SUNSPOT STRUCTURE [PDF]
Results of a three-dimensional MHD simulation of a sunspot with a photospheric size of about 20 Mm are presented. The simulation has been carried out with the MURaM code, which includes a realistic equation of state with partial ionization and radiative transfer along many ray directions.

Stream-aligned Magnetohydrodynamics for Solar Wind Simulations [PDF]
Abstract We present a reduced magnetohydrodynamic (MHD) mathematical model describing the dynamical behavior of highly conducting plasmas with frozen-in magnetic fields, constrained by the assumption that there exists a frame of reference, where the magnetic field vector,

Simulations of Incompressible Magnetohydrodynamic Turbulence [PDF]
We simulate incompressible MHD turbulence using a pseudospectral code. Our major conclusions are: (1) MHD turbulence is most conveniently described in terms of counterpropagating shear Alfven and slow waves. Shear Alfven waves control the cascade dynamics. Slow waves play a passive role and adopt the spectrum set by the shear Alfven waves.

SIMULATIONS OF ELECTRON MAGNETOHYDRODYNAMIC TURBULENCE
We present numerical simulations of electron magnetohydrodynamic (EMHD) and electron reduced MHD (ERMHD) turbulence. Comparing scaling relations, we find that both EMHD and ERMHD turbulence show similar spectra and anisotropy. We develop new techniques to study anisotropy of EMHD turbulence.

General relativistic magnetohydrodynamical simulations of the jet in M87 [PDF]
(abridged) The connection between black hole, accretion disk, and radio jet can be best constrained by fitting models to observations of nearby low luminosity galactic nuclei, in particular the well studied sources Sgr~A* and M87.

Striped Jets in Post–Neutron Star Merger Systems
Models invoking magnetic reconnection as the particle acceleration mechanism within relativistic jets often adopt a gradual energy dissipation profile within the jet. However, such a profile has yet to be reproduced in first-principles simulations.

The Formation of Star-forming Disks in the TNG50 Simulation
We investigate the disk formation process in the TNG50 simulation, examining the profiles of SFR surface density (Σ _SFR ), gas inflow and outflow, and the evolution of the angular momentum of inflowing gas particles.
