The Circumgalactic Medium [PDF]

Annual Review of Astronomy and Astrophysics, 2017
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 assumed an important role in our understanding of galaxy evolution owing to rapid advances in observational access to this diffuse, nearly invisible material ...

Constraining magnetic fields in the circumgalactic medium [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACTWe study the properties of magnetic fields in the circumgalactic medium (CGM) of z < 1 galaxies by correlating Faraday rotation measures (RMs) of ∼1000 high-redshift radio sources with the foreground galaxy number density estimated from the DESI Legacy Imaging Surveys.

The Impact of Starbursts on the Circumgalactic Medium [PDF]

The Astrophysical Journal, 2013
We present a study exploring the impact of a starburst on the properties of the surrounding circum-galactic medium (CGM): gas located beyond the galaxy's stellar body and extending out to the virial radius (200 kpc). We obtained ultraviolet spectroscopic

The circumgalactic medium of high redshift galaxies [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2014
We study the properties of the circumgalactic medium (CGM) of high-$z$ galaxies in the metal enrichment simulations presented in Pallottini et al. 2014. At $z=4$, we find that the simulated CGM gas density profiles are self-similar, once scaled with the ...

MUSEQuBES: characterizing the circumgalactic medium of redshift ≈3.3 Ly α emitters [PDF]

Monthly Notices of the Royal Astronomical Society, 2021
ABSTRACT We present the first characterization of the circumgalactic medium of Ly α emitters (LAEs), using a sample of 96 z ≈ 3.3 LAEs detected with the VLT/MUSE in fields centred on eight bright background quasars. The LAEs have low Ly α luminosities ($\sim 10^{42}\, \text{erg}\, \text{s}^{-1}$) and star formation rates (SFRs) $\sim 1 ...

The Study of the Circumgalactic Medium with Quasar Pairs

The Astrophysical Journal Supplement Series, 2023
We have collected 10,025 foreground–background quasar pairs with projected distances d _p < 500 kpc from the large quasar catalog of the Sloan Digital Sky Survey DR16Q. We investigate the properties of the Mg ii absorption lines with W _r > 0.15 Å around

The hidden circumgalactic medium

, 2019
The cycling of baryons in and out of galaxies is what ultimately drives galaxy formation and evolution. The circumgalactic medium (CGM) represents the interface between the interstellar medium and the cosmic web, hence its properties are directly shaped ...

The Anisotropic Circumgalactic Medium of Sub-L* Galaxies

The Astrophysical Journal
Using stacked emission-line flux measurements of cool circumgalactic gas (CGM) in lower-mass galaxies (10 ^9.0 ≤ M _* / M _⊙ ≤ 10 ^10.2 ), we measure the dependence of the emission characteristics on orientation relative to the disk plane as a function ...

The Circumgalactic Medium in Massive Halos [PDF]

, 2016
This chapter presents a review of the current state of knowledge on the cool (T ~ 1e4 K) halo gas content around massive galaxies at z ~ 0.2-2. Over the last decade, significant progress has been made in characterizing the cool circumgalactic gas in ...

The Truncated Circumgalactic Medium of the Large Magellanic Cloud

The Astrophysical Journal Letters
The Large Magellanic Cloud (LMC) is the nearest massive galaxy to the Milky Way (MW). Its circumgalactic medium (CGM) is complex and multiphase, containing both stripped H i structures like the Magellanic Stream and Bridge and a diffuse warm corona seen ...
