The origin of cold gas in the circumgalactic medium

Astronomy & Astrophysics
Context. The presence of cold gas (T ≲ 104 K) in the circumgalactic medium (CGM) of galaxies has been confirmed in observations and in high-resolution simulations, but its origin is still a puzzle. Possible mechanisms are cold accretion from the intergalactic medium (IGM), clumps embedded in outflows and transported from the disk, and gas detaching ...

Mapping the z ∼ 2 Circumgalactic Medium with KBSS Galaxy Pairs

The Astrophysical Journal
We present new results on the spatial structure and kinematics of the circumgalactic medium (CGM) of z  ∼ 2 star-forming galaxies drawn from the Keck Baryonic Structure Survey, using Ly α and metallic ion absorption recorded in spectra of background ...

Mapping the Imprints of Stellar and Active Galactic Nucleus Feedback in the Circumgalactic Medium with X-Ray Microcalorimeters

Astrophysical Journal
The Astro2020 Decadal Survey has identified the mapping of the circumgalactic medium (CGM; the gaseous plasma around galaxies) as a key objective. We explore the prospects for characterizing the CGM in and around nearby galaxy halos with a future large ...

Improving Photometric Redshifts of Epoch of Reionization Galaxies: A New Empirical Transmission Curve with Neutral Hydrogen Damping Wing Lyα Absorption

The Astrophysical Journal Letters
We present a new analytical model for the attenuation to Epoch of Reionization (EoR) galaxies by proximate neutral hydrogen gas. Many galaxy spectra in the EoR taken by JWST have shown a flux deficit at wavelengths just redward of the Lyman break, and ...

FEASTS: Radial Distribution of H i Surface Densities Down to 0.01 M⊙ pc−2 of 35 Nearby Galaxies

The Astrophysical Journal
We present the H i surface density (Σ _H _i ) radial distributions based on total-power H i images obtained by FAST in the FEASTS program, for 35 galaxies with inclinations lower than 72°.

The MUSECuBES surveys on the circumgalactic medium

, 2019
The circumgalactic medium (CGM) is a dynamic, complex, multiphase, metal-enriched gas reservoir surrounding galaxies which harbors gas and metal masses comparable to those in galaxies themselves. Using a large quantity of spectral and imaging data obtained with MUSE & UVES on the VLT and ACS & COS on-board HST, we have started a major campaign ...
