The Deep Learning Halo Definer: A Multimodal Framework for Halo Mass and Gas Fraction Inference on Galaxy Groups and Clusters
Caleb Ogle, Kalvyn N. Poncelet Adams, Benjamin D. Oppenheimer +5
Accurately inferring dark matter halo properties like the total halo mass (M_{halo}) and gas fractions (f_{gas}) remains particularly challenging at group scales, where low member…
X-ray emission signatures of galactic feedback in the hot circumgalactic medium: predictions from cosmological hydrodynamical simulations
Emily M. Silich, John ZuHone, Elena Bellomi +6
Little is currently known about the physical properties of the hot circumgalactic medium (CGM) surrounding massive galaxies. Next-generation X-ray observatories will enable detaile…
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,…
X-raying CAMELS: Constraining Baryonic Feedback in the Circum-Galactic Medium with the CAMELS simulations and eRASS X-ray Observations
Erwin T. Lau, Daisuke Nagai, Ákos Bogdán +7
The circumgalactic medium (CGM) around massive galaxies plays a crucial role in regulating star formation and feedback. Using the CAMELS simulation suite, we develop emulators for…
Quantifying Baryonic Feedback on Warm-Hot Circumgalactic Medium in CAMELS Simulations
Isabel Medlock, Chloe Neufeld, Daisuke Nagai +6
The baryonic physics shaping galaxy formation and evolution are complex, spanning a vast range of scales and making them challenging to model. Cosmological simulations rely on subg…
Equilibrium States of Galactic Atmospheres II: Interpretation and Implications
G. M. Voit, C. Carr, D. B. Fielding +5
The scaling of galaxy properties with halo mass suggests that feedback loops regulate star formation, but there is no consensus yet about how those feedback loops work. To help cla…
Equilibrium States of Galactic Atmospheres I: The Flip Side of Mass Loading
G. M. Voit, V. Pandya, D. B. Fielding +5
This paper presents a new framework for understanding the relationship between a galaxy and its circumgalactic medium (CGM). It focuses on how imbalances between heating and coolin…
The COS CGM Compendium. II: Metallicities of the Partial and Lyman Limit Systems at z<1
Christopher B. Wotta, Nicolas Lehner, J. Christopher Howk +3
We present the results from our COS circumgalactic medium (CGM) compendium (CCC), a survey of the CGM at z<1 using HI-selected absorbers with 15<log N(HI) <19. We focus here on 82…
The COS CGM Compendium (CCC). I: Survey Design and Initial Results
Nicolas Lehner, Christopher B. Wotta, J. Christopher Howk +3
We present a neutral hydrogen-selected absorption-line survey of gas with HI column densities 15<log N(HI)<19 at z<1 using the Cosmic Origins Spectrograph on the Hubble Space Teles…
