Galactic winds driven by cosmic ray streaming

Monthly Notices of the Royal Astronomical Society, 2012
Galactic winds are observed in many spiral galaxies with sizes from dwarfs up to the Milky Way, and they sometimes carry a mass in excess of that of newly formed stars by up to a factor of ten. Multiple driving processes of such winds have been proposed,

CLASSY. VI. The Density, Structure, and Size of Absorption-line Outflows in Starburst Galaxies

The Astrophysical Journal, 2023
Galaxy formation and evolution are regulated by the feedback from galactic winds. Absorption lines provide the most widely available probe of winds.

Resolved Velocity Profiles of Galactic Winds at Cosmic Noon

The Astrophysical Journal, 2023
We study the kinematics of the interstellar medium (ISM) viewed “down the barrel” in 20 gravitationally lensed galaxies during cosmic noon ( z = 1.5–3.5).

Metal enrichment of the intra-cluster medium by thermally and cosmic-ray driven galactic winds [PDF]

, 2009
We investigate the efficiency and time-dependence of thermally and cosmic ray driven galactic winds for the metal enrichment of the intra-cluster medium (ICM) using a new analytical approximation for the mass outflow.

Metal enrichment of the intra-cluster medium over a Hubble time for merging and relaxed galaxy clusters [PDF]

, 2007
We investigate the efficiency of galactic mass loss, triggered by ram-pressure stripping and galactic winds of cluster galaxies, on the chemical enrichment of the intra-cluster medium (ICM).

Galactic Winds in Low-Mass Galaxies [PDF]

Proceedings of the International Astronomical Union, 2018
AbstractMass-loss via stellar-feedback driven outflows is predicted to play a critical role in the baryon cycle of low-mass galaxies. However, observational constraints on warm winds are limited as outflows are transient, intrinsically low-surface brightness events and, thus, difficult to detect.

Magnetic Fields Around Galactic Discs

Galaxies, 2019
Magnetic fields in the discs of spiral galaxies are quite well understood, although, of course, many details still require investigation and future observations with new generations of radio telescopes will be valuable here.

Discovery of a Spatially and Kinematically Resolved 55 kpc Scale Superbubble Inflated by an Intermediate-redshift Non-BAL Quasar

The Astrophysical Journal Letters, 2023
We report on the discovery of a rare case of spatially and kinematically resolved galactic-scale outflow at intermediate redshift based on VLT/MUSE optical integral field spectroscopic observation of the quasar HE 0238–1904.
