H I Properties of Field Galaxies at -0.6: Insights into Declining Cosmic Star Formation
David DePalma, Neeraj Gupta, Hsiao-Wen Chen +18
We report statistically significant detection of H I 21-cm emission from intermediate-redshift (-0.6) galaxies. By leveraging multi-sightline galaxy survey data from t…
Spatially Resolved Properties of Extraplanar Diffuse Ionized Gas in NGC3511 and NGC3513
Hanjue Zhu, Erin Boettcher, Hsiao-Wen Chen
Gaseous, disk-halo interfaces are shaped by processes that are critical to galaxy evolution, including gas accretion and outflows. Extraplanar diffuse ionized gas (eDIG) layers are…
The Cosmic Ultraviolet Baryon Survey (CUBS) IX: The enriched circumgalactic and intergalactic medium around star-forming field dwarf galaxies traced by O VI absorption
Nishant Mishra, Sean D. Johnson, Gwen C. Rudie +13
The shallow potential wells of star-forming dwarf galaxies make their surrounding circumgalactic and intergalactic medium (CGM/IGM) sensitive laboratories for studying the inflows…
Illuminating the Incidence of Extraplanar Dust Using Ultraviolet Reflection Nebulae with GALEX
Erin Boettcher, Edmund Hodges-Kluck
Circumgalactic dust grains trace the circulation of mass and metals between star-forming regions and gaseous galactic halos, giving insight into feedback and tidal stripping proces…
