Three dimensional simulations of Hall magnetohydrodynamics [PDF]
AbstractTurbulent flows take place in a large variety of astrophysical objects, and often times are the source of dynamo generated magnetic fields. Much of the progress in our understanding of dynamo mechanisms, has been made within the theoretical framework of magnetohydrodynamics (MHD).

Fluctuation Dynamos in Supersonic Turbulence at Pm ≳ 1
Fluctuation dynamos provide a robust mechanism for amplifying weak seed magnetic fields in turbulent astrophysical plasmas. However, their behaviour in the highly compressible regimes characteristic of the interstellar medium remains incompletely ...

Global Magnetohydrodynamical Simulations of Accretion Tori
Global time-dependent simulations provide a means to investigate time-dependent dynamic evolution in accretion disks. This paper seeks to extend previous local simulations by beginning a systematic effort to develop fully global three-dimensional simulations.

The Life and Times of Star-forming Cores: An Analysis of Dense Gas in the STARFORGE Simulations
Dense gas in molecular clouds is an important signature of ongoing and future star formation. We identify and track dense cores in the starforge simulations, following the core evolution from birth through dispersal by stellar feedback for typical Milky ...

The Interaction of a Supernova Remnant with Background Interstellar Turbulence
Supernova explosions are among the most energetic events in the Universe. After the explosion, the material ejected by the supernova expands throughout the interstellar medium (ISM), forming what is called a supernova remnant (SNR). The shocks associated

Cosmic-Ray Acceleration of Galactic Outflows in Multiphase Gas
We investigate the dynamical interaction between cosmic rays (CRs) and the multiphase interstellar medium (ISM) using numerical magnetohydrodynamic (MHD) simulations with a two-moment CR solver and TIGRESS simulations of star-forming galactic disks.
