Simulations of Relativistic Force‐free Magnetohydrodynamic Turbulence
The Astrophysical Journal, 2005 We present numerical studies of 3-dimensional magnetohydrodynamic (MHD) turbulence in a strongly magnetized medium in the extremely relativistic limit, in which the inertia of the charge carriers can be neglected. We have focused on strong Alfvenic turbulence in the limit. We have found the following results.

The Life and Times of Star-forming Cores: An Analysis of Dense Gas in the STARFORGE Simulations
The Astrophysical JournalDense 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
The Astrophysical Journal Supplement SeriesSupernova 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
The Astrophysical JournalWe 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.

The Impact of Enhanced Extreme-ultraviolet Flux on the Upper Atmosphere of Earth-like Exoplanets
The Astrophysical JournalIdentifying Earth-like planets outside our solar system is a leading research goal in astronomy, but determining if candidate planets have atmospheres, and more importantly if they can retain atmospheres, is still out of reach.

Odd Radio Circles Modeled by Shock-bubble Interactions
The Astrophysical JournalThe physical nature and origins of the newly discovered class of Odd Radio Circles (ORCs) remain unclear. We investigate a model whereby ORCs are synchrotron-emitting vortex rings formed by the Richtmyer–Meshkov instability (RMI) when a shock interacts ...

Effects of Dynamo-generated Large-scale Magnetic Fields on the Surface Gravity (f) Mode
The Astrophysical Journal LettersBy modeling the upper layers of the Sun in terms of a two-layer setup where a free surface exists within the computational domain, we numerically study the interaction between the surface gravity, or the fundamental ( f ) mode, and the magnetic fields ...
