Ninety per cent of baryons are located outside galaxies, either in the circumgalactic or intergalactic medium1,2. Theory points to galactic winds as the primary source of the enriched and massive circumgalactic medium3–6. Winds from compact starbursts have been observed to flow to distances somewhat greater than ten kiloparsecs7–10, but the circumgalactic medium typically extends beyond a hundred kiloparsecs3,4. Here we report optical integral field observations of the massive but compact… 
A Comparison of Circumgalactic Mg ii Absorption between the TNG50 Simulation and the MEGAFLOW Survey
The circumgalactic medium (CGM) contains information on gas flows around galaxies, such as accretion and supernova-driven winds, which are difficult to constrain from observations alone. Here, we use
Compact Starburst Galaxies with Fast Outflows: Central Escape Velocities and Stellar Mass Surface Densities from Multiband Hubble Space Telescope Imaging
We present multiband Hubble Space Telescope imaging that spans rest-frame near-ultraviolet through near-infrared wavelengths ( –1.1 μm) for 12 compact starburst galaxies at z = 0.4–0.8. These massive
MusE GAs FLOw and Wind (MEGAFLOW) IV. A two sightline tomography of a galactic wind
Galactic outflows are thought to eject baryons back out to the circum-galactic medium (CGM). Studies based on metal absorption lines (MgII in particular) in the spectra of background quasars indicate
Physical Properties of Massive Compact Starburst Galaxies with Extreme Outflows
We present results on the nature of extreme ejective feedback episodes and the physical conditions of a population of massive (M * ∼ 1011 M ⊙), compact starburst galaxies at z = 0.4–0.7. We use data
Aspera: the UV SmallSat telescope to detect and map the warm-hot gas phase in nearby galaxy halos
Aspera is an extreme-UV (EUV) Astrophysics small satellite telescope designed to map the warm-hot phase coronal gas around nearby galaxy halos. Theory suggests that this gas is a significant fraction
Cool outflows in galaxies and their implications
Neutral-atomic and molecular outflows are a common occurrence in galaxies, near and far. They operate over the full extent of their galaxy hosts, from the innermost regions of galactic nuclei to the
An Exquisitely Deep View of Quenching Galaxies through the Gravitational Lens: Stellar Population, Morphology, and Ionized Gas
This work presents an in-depth analysis of four gravitationally lensed red galaxies at z = 1.6–3.2. The sources are magnified by factors of 2.7–30 by foreground clusters, enabling spectral and
Deviations from the Infrared-radio Correlation in Massive, Ultracompact Starburst Galaxies
Feedback through energetic outflows has emerged as a key physical process responsible for transforming star-forming galaxies into the quiescent systems observed in the local universe. To explore this
A 60 kpc Galactic Wind Cone in NGC 3079
Galactic winds are associated with intense star formation and AGNs. Depending on their formation mechanism and velocity they may remove a significant fraction of gas from their host galaxies, thus
The Structure of Multiphase Galactic Winds
We present a novel analytic framework to model the steady-state structure of multiphase galactic winds comprised of a hot, volume-filling component and a cold, clumpy component. We first derive

Numerical simulations suggest that active galactic nuclei (AGNs) play an important role in the formation of early-type galaxies by expelling gas and dust in powerful galactic winds and quenching star
Fast winds drive slow shells: a model for the circumgalactic medium as galactic wind-driven bubbles
Successful models of the low redshift circumgalactic medium (CGM) must account for (1) a large amount of gas, (2) relatively slow gas velocities, (3) a high degree of metal enrichment, (4) the

Suppression of star formation in the galaxy NGC 253 by a starburst-driven molecular wind
TLDR
Observations of NGC 253, a nearby starburst galaxy known to possess a wind, are reported that trace the cool molecular wind at 50-parsec resolution, allowing us to determine that the molecular outflow rate is greater than 3 solar masses per year and probably about 9 solar massesper year, indicating that the starburst-driven wind limits the star-formation activity and the final stellar content.
Stellar feedback as the origin of an extended molecular outflow in a starburst galaxy
TLDR
Observations of molecular gas in a compact (effective radius 100 parsecs) massive starburst galaxy at redshift 0.7, which is known to drive a fast outflow of ionized gas, find that 35 per cent of the total molecular gas extends approximately 10 kiloparsecs, and one-third of this extended gas has a velocity of up to 1,000 kilometres per second.

The under-abundance of very massive galaxies in the universe is frequently attributed to the effect of galactic winds. Although ionized galactic winds are readily observable most of the expelled mass

The gas surrounding galaxies outside their disks or interstellar medium and inside their virial radii is known as the circumgalactic medium (CGM). In recent years this component of galaxies has

TLDR
The data indicate that ionized oxygen is a basic component of nearly all star-forming galaxies that is removed or transformed during the quenching of star formation and the transition to passive evolution.
