H I 21 cm Absorption Associated with Foreground Galaxies on Top of Quasars

The Astrophysical Journal
A systematic search for H i 21 cm absorption in quasar–galaxy pairs (QGPs) provides a powerful means to map the distribution of cold gas around high-redshift star-forming galaxies.

The Two-component Circumgalactic Medium Emission around z ∼ 2 Radio-loud Quasars

The Astrophysical Journal
We present Ly α , He ii , and C iv observations of seven z ∼ 2 radio-loud quasars observed using the Keck Cosmic Web Imager and compare it to observed radio jet emission using archival Very Large Array and Atacama Large Millimeter/submillimeter Array ...

Probing the He ii Reionization ERA via Absorbing C iv Historical Yield (HIERACHY). III. The C iv Absorber Catalog and Initial Results on Cosmic Abundance Evolution at z ≈ 3–5

The Astrophysical Journal
As part of the HIERACHY program, we collect the high signal-to-noise ratio and high-spectral resolution optical spectra of 25 quasars at z  ≈ 4–5 to constrain the C iv evolution at z  ≈ 3–5.

Studying the Circumgalactic Medium with MeerKAT

In order to understand how galaxies accrete gas from their surroundings and the impacts of feedback on quenching this accretion, it is necessary to study the circumgalactic medium (CGM).  While we have estimates of the total mass and metallicity of the CGM from UV absorption line studies, in order to understand the flow of gas onto and out of galaxy ...

EIGER IV. The Cool 104 K Circumgalactic Environment of High-redshift Galaxies Reveals Remarkably Efficient Intergalactic Medium Enrichment

We report new observations of the cool diffuse gas around 29, 2.3 1.3 R _200 ), suggest that five out of the seven Mg ii absorption systems are not gravitationally bound to their host galaxy.
