Hydrodynamic and magnetohydrodynamic simulations of wire turbulence [PDF]
High Energy Density Physics, 2019 We report on simulations of laboratory experiments in which magnetized supersonic flows are driven through a wire mesh. The goal of the study was to investigate the ability of such a configuration to generate supersonic, MHD turbulence. We first report on the morphological structures that develop in both magnetized and non-magnetized cases.

Striped Jets in Post–Neutron Star Merger Systems
The Astrophysical Journal, 2023 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.

Three‐dimensional Magnetohydrodynamic Simulations of Spherical Accretion [PDF]
The Astrophysical Journal, 2002 We present three-dimensional numerical magnetohydrodynamic simulations of radiatively inefficient spherical accretion onto a black hole. The simulations are initialized with a Bondi flow, and with a weak, dynamically unimportant, large-scale magnetic field. The magnetic field is amplified as the gas flows in.

Solar Wind and its Evolution [PDF]
, 2011 By using our previous results of magnetohydrodynamical simulations for the solar wind from open flux tubes, I discuss how the solar wind in the past is different from the current solar wind.

The Formation of Star-forming Disks in the TNG50 Simulation
The Astrophysical Journal, 2023 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.

The Astrophysical Journal Supplement Series, 2023 A new magnetohydrodynamics (MHD) simulation model of the global solar corona and solar wind is presented. The model covers the range of heliocentric distance from 2.5 solar radii, so that coronal mass ejections at the earliest phase near the Sun can be ...

TWO-DIMENSIONAL MAGNETOHYDRODYNAMIC SIMULATIONS OF BARRED GALAXIES [PDF]
The Astrophysical Journal, 2012 Barred galaxies are known to possess magnetic fields that may affect the properties of bar substructures such as dust lanes and nuclear rings. We use two-dimensional high-resolution magnetohydrodynamic (MHD) simulations to investigate the effects of magnetic fields on the formation and evolution of such substructures as well as on the mass inflow rates

The Astrophysical Journal, 2023 In this paper, we present a new tool to investigate the interaction of the solar wind with Venus with the approach of a global multifluid magnetohydrodynamics (MHD) model. The continuity, momentum, and energy equations for H ^+ , O ^+ , ${{\rm{O}}}_{2}^{+
