Geometry, Dissipation, Cooling, and the Dynamical Evolution of Wind-Blown Bubbles
Lachlan Lancaster, Eve C. Ostriker, Chang-Goo Kim +2
Bubbles driven by energy and mass injection from small scales are ubiquitous in astrophysical fluid systems and essential to feedback across multiple scales. In particular, O stars…
Cosmic-Ray Acceleration of Galactic Outflows in Multiphase Gas
Lucia Armillotta, Eve C. Ostriker, Chang-Goo Kim +1
We investigate the dynamical interaction between cosmic rays (CRs) and the multiphase interstellar medium (ISM) using numerical magnetohydrodynamic (MHD) simulations with a two-mom…
Implementation of chemistry in the Athena++ code
Munan Gong, Ka-Wai Ho, James M. Stone +6
Chemistry plays a key role in many aspects of astrophysical fluids. Atoms and molecules are agents for heating and cooling, determine the ionization fraction, serve as observationa…
Effects of Magnetic Fields on Gas Dynamics and Star Formation in Nuclear Rings
Sanghyuk Moon, Woong-Tae Kim, Chang-Goo Kim +1
Nuclear rings at the centers of barred galaxies are known to be strongly magnetized. To explore the effects of magnetic fields on star formation in these rings and nuclear gas flow…
Arkenstone I: A Novel Method for Robustly Capturing High Specific Energy Outflows In Cosmological Simulations
Matthew C. Smith, Drummond B. Fielding, Greg L. Bryan +11
Arkenstone is a new model for multiphase, stellar feedback driven galactic winds designed for inclusion in coarse resolution cosmological simulations. In this first paper of a seri…
The structure and composition of multiphase galactic winds in a Large Magellanic Cloud mass simulated galaxy
Ulrich P. Steinwandel, Chang-Goo Kim, Greg L. Bryan +3
We present the first results from a high resolution simulation with a focus on galactic wind driving for an isolated galaxy with a halo mass of M (similar…
