Highly Ionized Oxygen in the Circumgalactic Medium of TNG100 Galaxies: Distributions, Thermal States, and Ionization Mechanisms
Yossi Oren, Amiel Sternberg, Christopher F. McKee +1
We investigate the origin of the highly ionized oxygen species, O VI, O VII, and O VIII, in the circumgalactic medium (CGM) of galaxies at redshifts , by post-processi…
The Halo Gas of Local Spiral Galaxies and the Link to Gaseous Satellites
Yong Zheng, Jingyao Zhu, Ben Wertz +2
Gaseous satellites orbiting massive host galaxies experience gas stripping and may contribute additional gas to the hosts' circumgalactic medium (CGM). We identify a sample of 21 l…
Radio Recombination Line Contamination in Post-Reionization 21 cm Intensity Mapping
Pip Petersen, Yakov Faerman, Matthew McQuinn
We explore radio recombination line (RRL) contamination in post-reionization 21 cm intensity mapping observations. We develop a formalism to estimate the contamination of the 21 cm…
Revealing Cosmic Ecosystems with the Hubble Space Telescope in 2030s and Beyond

Ultraviolet spectroscopy with the Hubble Space Telescope (HST) provides the most direct and sensitive probe of the disk-circumgalactic medium (CGM) interface at radii of 20 kpc, wh…
High-S/N Quasar Observations with HST/COS: Deep Fields for Spectroscopy
Andrew J. Fox, Jerry Kriss, Philipp Richter +49
Hubble is still in prime observing condition for making transformative discoveries in UV astronomy. In this white paper we describe the science case for a deep (S/N>30) UV spectros…
Accretion-Driven Turbulence in the Circumgalactic Medium
Roy Goldner, Jonathan Stern, Drummond Fielding +3
Simulations suggest that turbulence is ubiquitous in the circumgalactic medium (CGM), though the source and properties of CGM turbulence is uncertain. Using analytic considerations…
Modeling Emission-Line Surface Brightness in a Multiphase Galactic Wind: An O VI Case Study
Zirui Chen, Zixuan Peng, Kate H. R. Rubin +6
We present a fast and robust analytic framework for predicting surface brightness (SB) of emission lines in galactic winds as a function of radius up to kpc out in the c…
Mapping Galactic Winds and Small-scale Structure in the Circumgalactic Medium with Habitable Worlds Observatory
Joseph N. Burchett, Deborah M. Lokhorst, Yakov Faerman +4
We present a science case for the Habitable Worlds Observatory (HWO) to map the circumgalactic medium (CGM) in emission by targeting ultraviolet emission lines, which trace the 10^…
Introducing the Descriptive Parametric Model: Gaseous Profiles for Galaxies, Groups, and Clusters
Benjamin D. Oppenheimer, G. Mark Voit, Yannick M. Bahé +14
We develop and present the Descriptive Parametric Model (DPM), a tool for generating profiles of gaseous halos (pressure, electron density, and metallicity) as functions of radius,…
Marvelous Metals: Surveying the Circumgalactic Medium of Simulated Dwarf Galaxies
Daniel R. Piacitelli, Alyson M. Brooks, Charlotte Christensen +7
Dwarf galaxies are uniquely sensitive to energetic feedback processes and are known to experience substantial mass and metal loss from their disk. Here, we investigate the circumga…
Upper Limits on the Mass of Cool Gas in the Circumgalactic Medium of Dwarf Galaxies
Yakov Faerman, Yong Zheng, Benjamin D. Oppenheimer
We use HI absorption measurements to constrain the amount of cool ( K), photoionized gas in the circumgalactic medium (CGM) of dwarf galaxies with $M_* = 10^{6.5-9.5}…
The CIViL* Survey: The Discovery of a C IV Dichotomy in the CGM of L* Galaxies
Samantha L. Garza, Jessica K. Werk, Trystyn A. M. Berg +4
This paper investigates C IV absorption in the circumgalactic medium (CGM) of L* galaxies and its relationship with galaxy star formation rates. We present new observations from th…
The Statistics and Environments of Hostless Supernovae
Yu-Jing Qin, Ann Zabludoff, Iair Arcavi +3
Transient surveys routinely detect supernovae (SNe) without obvious host galaxies. To understand the demographics of these "hostless" SNe and to constrain the possible host propert…
