Spatially Resolved Circumgalactic Medium around a Star-forming Galaxy Driving a Galactic Outflow at z ≈ 0.8

The Astrophysical Journal
We report the small-scale spatial variation in cool ( T  ∼ 10 ^4 K) Mg ii absorption detected in the circumgalactic medium (CGM) of a star-forming galaxy at z  ≈ 0.8.

Deep Ultraviolet, Emission-line Imaging of the Makani Galactic Wind

The Astrophysical Journal
The O vi 1032, 1038 Å line is a key probe of cooling gas in the circumgalactic medium (CGM) of galaxies but has been observed to date primarily in absorption along single sight lines.

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.

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.

Equilibrium States of Galactic Atmospheres. II. Interpretation and Implications

The Astrophysical Journal
The scaling of galaxy properties with halo mass suggests that feedback loops regulate star formation, but there is no consensus yet about how those feedback loops work. To help clarify discussions of galaxy-scale feedback, Paper I presented a very simple

Illuminating the Incidence of Extraplanar Dust Using Ultraviolet Reflection Nebulae with GALEX

The Astrophysical Journal
Circumgalactic dust grains trace the circulation of mass and metals between star-forming regions and gaseous galactic halos, giving insight into feedback and tidal stripping processes.
