Forming Molecular Hydrogen in a Galaxy Halo Through Star Formation Wind Interactions
Brad Koplitz, Sanchayeeta Borthakur, Timothy Heckman +5
Molecular hydrogen (H) is the key ingredient for star formation in galaxies. However, how H is distributed in and around galaxies is an open question in astronomy. We repor…
SQuIGGE: Ubiquitous Cool Gas Outflows with Large Mass-Loading Factors in Post-starburst Galaxies
Yuanze Luo, Justin S. Spilker, David J. Setton +13
While recent James Webb Space Telescope studies have highlighted cool gas outflows as an important mechanism for rapid quenching at , such space-based spectroscopic samp…
Tracing Interstellar Gas in Quiescent Galaxies Using Na I D and Ca II H&K Absorption
Arian Moghni, Timothy M. Heckman, Namrata Roy +3
For over two decades, Na I D ( Å) absorption has been the primary optical tracer of cool, neutral gas in galaxies. In contrast, Ca II H&K (3934.78, 39…
Resonantly Scattered CIV Emission in Local Star-forming Galaxies: Radiative Transfer Constraints on High-ionization Gas in Reionization Analogs
Zhihui Li, Danielle A. Berg, Simon Gazagnes +4
Rest-frame ultraviolet emission lines are diagnostics of hard ionizing spectra and highly ionized gas in galaxies resembling the sources of cosmic reionization. Nebular CIV emissio…
CLASSY. XV. Kinematics and Spatial Distributions of Outflows in Local Highly Star-Forming Galaxies
Mason S. Huberty, Cody A. Carr, Claudia Scarlata +17
Star-forming galaxies drive massive outflows that play an important role in galaxy evolution by regulating feedback and influencing the dynamics of surrounding media. Measuring gal…
Lighting Up the CGM: Strong, Jet-Aligned Emission around Radio Galaxies
Namrata Roy, Sanchayeeta Borthakur, Timothy Heckman +1
A primary question within galaxy evolution is how active galactic nuclei (AGN) feedback modifies the circumgalactic medium (CGM). We present a search for faint H emission from t…
Unprecedented Constraints on Gas Flows at High Redshift Using Deep JWST/NIRSpec Observations from the LyC22, EXCELS, and AURORA Surveys
Emily Kehoe, Alice E. Shapley, Adam C. Carnall +25
We investigate how low-ionization gas flows in typical star-forming galaxies at depend on galaxy intrinsic properties and viewing angle. For this analysis we use JWST/NIRS…
Revealing Cosmic Ecosystems with the Hubble Space Telescope in 2030s and Beyond
Sanchayeeta Borthakur, Tanmay Singh, David French +22
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…
MusE GAs FLOw and Wind (MEGAFLOW) XIV: Background-Galaxy Absorption Reveals Kiloparsec-Scale Structure in the Cool Circumgalactic Medium
Yucheng Guo, Nicolas F. Bouché, Martin Wendt +9
The properties of the cool (~K) gas in the circumgalactic medium (CGM) are closely linked to the physical mechanisms that create and maintain this multiphase medium. The…
The Importance of Galaxy-Wide Star Formation in Driving Winds at z~1
Weichen Wang, Susan A. Kassin, S. M. Faber +11
In this work, we study winds for a representative sample of 86 star-forming galaxies (SFGs) at z~1 with , by measuring the Mg II line profiles…
The short and long of iPhoton science for a boosted Hubble
Stephan R. McCandliss, Jack Ford, Anne E. Jaskot +7
Boosting the Hubble Space Telescope (HST) will provide unique opportunities to carry out precursor science for the Habitable Worlds Observatory (HWO). Chief among them are science…
The Small-scale Structures in the Wind of Messier 82
Yucheng Guo, Timothy Heckman, Sanchayeeta Borthakur +10
Small-scale multiphase structure plays a central role in galactic-wind evolution, yet the parsec-scale morphology and excitation of the warm ionised gas remain poorly constrained.…
Resolving the Unresolved Galactic Winds in Multi-phase Models. I. Methodology and Application
Xinfeng Xu, Drummond Fielding, Timothy Heckman +12
Galactic winds shape galaxy evolution; however, the outflowing gas is complex: it consists of multiple ionization phases, and its properties vary spatially. Therefore, methods that…
The Prevalence of Turbulence-Regulated Multiphase Galactic Winds in Star-Forming Galaxies
Zhihui Li, Timothy Heckman, Max Gronke +8
We build upon our previously developed multi-ion radiative transfer (RT) framework, PEACOCK, to investigate the kinematic and energetic structure of cool-to-warm galactic winds in…
Kinematically Coherent Multiphase Galactic Winds in Star-Forming Galaxies Revealed by Unified Radiative Transfer Modeling of UV Emission and Absorption Lines
Zhihui Li, Timothy Heckman, Max Gronke +8
We present PEACOCK, a three-dimensional Monte Carlo radiative transfer (RT) framework designed to self-consistently model rest-frame ultraviolet emission and absorption lines arisi…
