MUSEQuBES: The Column Density, Covering Fraction, and Mass of O vi-bearing Gas in and Around Low-redshift Galaxies

The Astrophysical Journal
We present a study of O vi -bearing gas around 247 low-mass (median ${\mathrm{log}}_{10}({M}_{\star }/{M}_{\odot })$ = 8.7) galaxies at low redshifts (0.1 < z < 0.7) using background quasars as part of the MUSE Quasar-fields Blind Emitters Survey ...

DUST IN THE CIRCUMGALACTIC MEDIUM OF LOW-REDSHIFT GALAXIES [PDF]

The Astrophysical Journal, 2015
Using spectroscopically selected galaxies from the Sloan Digital Sky Survey we present a detection of reddening due to dust in the circumgalactic medium of galaxies. We detect the mean change in the colors of "standard crayons" correlated with the presence of foreground galaxies at z ~0.05 as a function of angular separation.

FEASTS Combined with Interferometry. IV. Mapping H i Emission to a Limit of NH i = 1017.7 cm−2 in Seven Edge-on Galaxies

The Astrophysical Journal
We present a statistical study of the neutral atomic hydrogen (H i ) gas extending into the circumgalactic medium perpendicular to the disk for seven edge-on galaxies with inclinations above 85° from the FEASTS program with a 3 σ (20 km s ^−1 ) column ...

Discovery of Optically Emitting Circumgalactic Nebulae around the Majority of UV-luminous Quasars at Intermediate Redshift

The Astrophysical Journal
We report the discovery of large, ionized, [O ii ]-emitting circumgalactic nebulae around the majority of 30 UV-luminous quasars at z = 0.4–1.4 observed with deep, wide-field integral field spectroscopy with the Multi-Unit Spectroscopy Explorer (MUSE) by

Unveiling the Sources of X-Ray Luminosity in DESI Galaxy Groups: Insights from the SRG/eROSITA All-sky Survey

The Astrophysical Journal
We use the first eROSITA all-sky survey to investigate the contributions of active galactic nuclei (AGN) and extended gas to the total X-ray luminosity ( L _X ) of galaxy groups with different halo masses ( M _h ) at different redshifts.

The kinetic Sunyaev–Zel'dovich tomography – II. Probing the circumgalactic medium [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
We propose the use of the kinetic Sunyaev-Zel'dovich (kSZ) effect to probe the circumgalactic medium (CGM), with the aid of a spectroscopic survey covering the same area of a SZ survey. One can design an optimal estimator of the kSZ effect of the CGM with a matched filter, and construct the cross correlation between the estimator and the peculiar ...

The Morphology and Kinematics of a Giant, Symmetric Nebula around a Radio-loud Quasar 3C 57: Extended Rotating Gas or Biconical Outflows?

The Astrophysical Journal
Gas flows between galaxies and the circumgalactic medium play a crucial role in galaxy evolution. When ionized by a quasar, these gas flows can be directly traced as giant nebulae. We present a study of a giant nebula around a radio-loud quasar, 3C 57 at
