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.

Cloud-by-cloud multiphase investigation of the circumgalactic medium of low-redshift galaxies [PDF]

Monthly notices of the Royal Astronomical Society
The pervasive presence of warm gas in galaxy halos suggests that the circumgalactic medium (CGM) is multiphase in its ionization structure and complex in its kinematics.

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 ...

It’s a Breeze: The Circumgalactic Medium of a Dwarf Galaxy Is Easy to Strip [PDF]

Astrophysical Journal
The circumgalactic medium (CGM) of star-forming dwarf galaxies plays a key role in regulating the galactic baryonic cycle. We investigate how susceptible the CGM of dwarf satellite galaxies is to ram pressure stripping in Milky Way–like environments.

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

Quantifying Baryonic Feedback on the Warm–Hot Circumgalactic Medium in CAMELS Simulations [PDF]

Astrophysical Journal
The baryonic physics shaping galaxy formation and evolution are complex, spanning a vast range of scales and making them challenging to model. Cosmological simulations rely on subgrid models that produce significantly different predictions. Understanding

ChemicalUniverseMachine. I. Uncovering the Cosmic Evolution of Metals in the Galaxy–Interstellar Medium–Circumgalactic Medium Ecosystem

Astrophysical Journal
We present an empirical chemical evolution model that explains the distribution of metals in the interstellar medium (ISM) and the circumgalactic medium (CGM) of galaxies based on the UniverseMachine and NeutralUniverseMachine models in the framework of ...

Outskirts of Distant Galaxies In Absorption

, 2016
QSO absorption spectroscopy provides a sensitive probe of both the neutral medium and diffuse ionized gas in the distant Universe. It extends 21cm maps of gaseous structures around low-redshift galaxies both to lower gas column densities and to higher ...

Not So Heavy Metals: Black Hole Feedback Enriches The Circumgalactic Medium [PDF]

, 2018
We examine the effects of SMBH feedback on the CGM using a cosmological hydrodynamic simulation \citep[{\sc Romulus25};][]{Tremmel2017} and a set of four zoom-in `genetically modified' Milky Way-mass galaxies sampling different evolutionary paths.

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 ...
