Observing Co-Located Neutral and Ionized Gas-Phase Iron Depletion in the Magellanic Clouds
Yun Qi Li, Jessica K. Werk, Caleb R. Choban +5
Depletion is the observed phenomenon where gas-phase elemental abundances are reduced through accretion onto dust grains. We measure neutral gas-phase elemental abundances (S, Fe)…

Christopher J. R. Clark, Julia. C. Roman-Duval, Suzanne C. Madden Marc Mertens +4
Carbon plays key roles in the InterStellar Medium (ISM) -- as a constituent of dust, as the carrier of the dominant far-infrared cooling line, and as a component of various importa…
The Metallicity Mapping of the Ionized Diffuse Gas at the Milky Way Disk-halo Interface
Bo-Eun Choi, Jessica K. Werk, Kirill Tchernyshyov +5
Metals in the diffuse, ionized gas at the boundary between the Milky Way's interstellar medium (ISM) and circumgalactic medium (CGM), known as the disk-halo interface (DHI), are va…
The COS-Holes Survey: Connecting Galaxy Black Hole Mass with the State of the CGM
Samantha L. Garza, Jessica K. Werk, Benjamin D. Oppenheimer +9
We present an analysis of \textit{HST}/COS/G160M observations of CIV in the inner circumgalactic medium (CGM) of a novel sample of eight z0, LL galaxies, p…
The Plane Quasar Survey: First Data Release
Jessica Werk, Kirill Tchernyshyov, Hannah Bish +4
We present a sample of 305 QSO candidates having , the majority with GALEX magnitudes NUV < 18.75. To generate this sample, we apply UV-IR color selection criteri…
METAL-Z: Measuring dust depletion in low metalicity dwarf galaxies
Aleksandra Hamanowicz, Kirill Tchernyshyov, Julia Roman-Duval +6
The cycling of metals between interstellar gas and dust is a critical aspect of the baryon cycle of galaxies, yet our understanding of this process is limited. This study focuses o…
Braving the Storm: Quantifying Disk-wide Ionized Outflows in the Large Magellanic Cloud with ULLYSES
Yong Zheng, Kirill Tchernyshyov, Knut Olsen +11
The Large Magellanic Cloud (LMC) is home to many HII regions, which may lead to significant outflows. We examine the LMC's multiphase gas ( K) in HI, SII, SiIV, and…
CGM CASBaH: The Mass Dependence of H~I Ly-Galaxy Clustering and the Extent of the CGM
Matthew C. Wilde, Kirill Tchernyshyov, Jessica K. Werk +9
We combine datasets from the CGM and CASBaH surveys to model a transition point, , between circumgalactic and intergalactic media (CGM and IGM, respectively).…
The CGM Survey: Quenching and the Transformation of the Circumgalactic Medium
Kirill Tchernyshyov, Jessica K. Werk, Matthew C. Wilde +9
This study addresses how the incidence rate of strong O VI absorbers in a galaxy's circumgalactic medium (CGM) depends on galaxy mass and, independently, on the amount of star form…

Julia Roman-Duval, Edward B. Jenkins, Kirill Tchernyshyov +9
The evolution of the metal content of the universe can be tracked through rest-frame UV spectroscopy of damped Ly- systems (DLAs). Gas-phase abundances in DLAs must be corrected…
