Upper Limits on the Mass of Cool Gas in the Circumgalactic Medium of Dwarf Galaxies

The Astrophysical Journal Letters
We use H i absorption measurements to constrain the amount of cool (≈10 ^4 K), photoionized gas in the circumgalactic medium (CGM) of dwarf galaxies with M _*  = 10 ^6.5−9.5 M _⊙ in the nearby Universe ( z

CLASSY. X. Highlighting Differences between Partial Covering and Semianalytic Modeling in the Estimation of Galactic Outflow Properties

The Astrophysical Journal
Feedback-driven massive outflows play a crucial role in galaxy evolution by regulating star formation and influencing the dynamics of surrounding media. Extracting outflow properties from spectral lines is a notoriously difficult process for a number of ...

Statistics for Galaxy Outflows at z ∼ 6–9 with Imaging and Spectroscopic Signatures Identified with JWST/NIRCam and NIRSpec Data

The Astrophysical Journal
We present statistics of z ∼ 6–9 galaxy outflows indicated by spatially extended gas emission and broad lines. With a total of 61 spectroscopically confirmed galaxies at z ∼ 6–9 in the JWST CEERS, GLASS, and ERO data, we find four galaxies with [O iii ] +

Gravitational arc-tomography of the circumgalactic medium

, 2019
Presentamos una aplicación de la “tomografía de arcos gravitacionales”, una técnica que devela la estructura morfológica y cinemática del gas enriquecido de forma coherente en galaxias formadoras de estrellas con corrimiento al rojo intermedio. Esta técnica pone condiciones de borde nuevas e independientes para entender la física de la formación de ...
