The Astrophysical Journal, 2022 Abstract We present hydrodynamical simulations of galactic winds from star-forming galaxies including nonequilibrium ionization and frequency-dependent radiative transfer, processes that have remained largely unaccounted for in galactic wind studies.

Time-dependent galactic winds [PDF]
Astronomy & Astrophysics, 2019 Context. Cosmic rays (CRs) are transported out of the galaxy by diffusion and advection due to streaming along magnetic field lines and resonant scattering off self-excited magnetohydrodynamic (MHD) waves. Thus momentum is transferred to the plasma via the frozen-in waves as a mediator assisting the thermal pressure in driving a galactic wind.

Cloud Properties in Simulated Galactic Winds
The Astrophysical JournalIn this work, we investigate the properties of a population of cool clouds in simulated galaxy outflows. Using data from the Cholla Galactic OutfLow Simulations (or CGOLS) isolated galaxy simulations, we generate catalogs of ∼10 ^5 clouds.

Galactic winds and the symmetry properties of galactic magnetic fields [PDF]
Astronomy and Astrophysics, 2010 Context. Contemporary studies of the symmetry properties of galactic magnetic fields contain two contradictory ideas. There are observational and theoretical hints that large-scale magnetic fields are symmetric with respect to the galactic plane in the disc, and antisymmetric in the halo.

Dust Survival in Galactic Winds
The Astrophysical JournalWe present a suite of high-resolution numerical simulations to study the evolution and survival of dust in hot galactic winds. We implement a novel dust framework in the Cholla hydrodynamics code and use wind tunnel simulations of cool, dusty clouds to ...

International Astronomical Union Colloquium, 1989 In the sequel we will be discussing that - apart from all other halo flows - it is highly probable that our Galaxy has a systematic mass loss; most other galaxies should behave in a similar way. This mass loss should occur in the form of a supersonic galactic wind provided the intergalactic pressure is low enough.

Dust entrainment in galactic winds [PDF]
, 2021 Winds driven by stellar feedback are an essential part of the galactic ecosystem and are the main mechanism through which low-mass galaxies regulate their star formation.
