Radio synchrotron emission, its polarization and Faraday rotation of the polarization angle
are powerful tools to study the strength and structure of magnetic fields in galaxies …

Star formation rates in the centers of disk galaxies often vastly exceed those at larger radii,
whether measured by the surface density of star formation Σ SFR, by the star formation rate …

We explore what dominant physical mechanism sets the kinetic energy contained in neutral,
atomic (H i) gas. Both supernova (SN) explosions and magnetorotational instability (MRI) …

The energy and momentum feedback from young stars has a profound impact on the
interstellar medium (ISM), including heating and driving turbulence in the neutral gas that …

We use vertically resolved numerical hydrodynamic simulations to study star formation and
the interstellar medium (ISM) in galactic disks. We focus on outer-disk regions where diffuse …

Modern extragalactic molecular gas surveys now reach the scales of star-forming giant
molecular clouds (GMCs; 20–50 pc). Systematic variations in GMC properties with galaxy …

We propose a new dynamical picture of galactic stellar and gas spirals, based on
hydrodynamic simulations in a" live" stellar disk. We focus especially on spiral structures …

We extend the description of the isotropic and anisotropic random component of the small-
scale magnetic field within the existing magnetic field model of the Milky Way from Jansson …

We study the instantaneous virial balance of CCs in numerical models of MCs. The models
represent a range of magnetic field strengths in MCs from subcritical to nonmagnetic …

Galactic disks consist of both stars and gas. The gas is more dynamically responsive than
the stars, and strongly nonlinear structures and velocities can develop in the interstellar …
