Spatially Resolved Nebular-Stellar Reddening with JWST/NIRISS
Peter J. Watson, Benedetta Vulcani, Tommaso Treu +7
An accurate determination of the dust attenuation within galaxies is essential to derive key physical properties such as the star formation rate (SFR). We present an analysis using…
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…
Astronomical Advantages of a Boost Mission to Facilitate HST Science into the 2030s: Imaging the Circumgalactic Medium of Galaxies
Matthew J. Hayes, Kate H. R. Rubin, Michelle A. Berg +20
We present the case for imaging ultraviolet line emission from highly ionized metals and HI Lya in the circumgalactic medium of galaxies, should the Hubble Space Telescope receive…
Extending Hubble into the 2030s to Resolve the Physics of LyC Escape
Cody Carr, Stephan McCandliss, Michelle Berg +6
Current observations with the James Webb Space Telescope (JWST) suggest that star-forming galaxies produce enough ionizing (LyC; nm) photons to drive cosmic reionization…
Witnessing the onset of stellar winds in Super-Luminous Supernova Hosts: implications for star-formation-driven outflows in low and high-redshift galaxies
A. Saldana-Lopez, A. Gkini, M. J. Hayes +6
Direct observational constraints on the earliest, stellar-wind-dominated phases of galactic outflows remain scarce. We present medium-resolution VLT/X-shooter spectroscopy of six T…
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…
