CNN-Based Inference of Gaseous Halo Properties from Synthetic X-ray and 21-cm HI Observations

Kalvyn N. Poncelet Adams, Benjamin D. Oppenheimer, Naomi Gluck +3

Quantifying the information content in multi-wavelength observations is critical for setting exposure times for upcoming X-ray and 21-cm HI radio surveys. We train convolutional ne…

COS-EDGES: Co-rotation and Kinematic Stratification of the Multi-Phase CGM Around Edge-On Galaxies

Glenn G. Kacprzak, Benjamin D. Oppenheimer, Nikole M. Nielsen +10

We present the first results from the COS-EDGES survey, targeting the kinematic connection between the ISM and multi-phase circumgalactic medium (CGM) in nine isolated, edge-on gal…

Extreme AGN feedback in the fossil galaxy group SDSSTG 4436

D. Eckert, F. Gastaldello, L. Lovisari +20

Supermassive black hole feedback is the currently favoured mechanism to regulate the star formation rate of galaxies and prevent the formation of ultra-massive galaxies ($M_\star>1…

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 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…
