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…
Studying Outflows with Synthetic Absorption Line Spectra from High Resolution Simulations
Jake Magee, Evan Schneider, Kate H. R. Rubin +2
Down-the-barrel absorption line spectra are a powerful probe of the properties of multiphase galactic outflows. In this work, we demonstrate a method to generate realistic syntheti…
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…
A Decade to Map the Diffuse Universe: FRB-QSO Pairs with HST/COS Spectroscopy
Jessica Werk, Matthew McQuinn, J. Xavier Prochaska +16
Jointly analyzing the sightlines of arcsecond-localized fast radio bursts (FRBs) and UV-bright quasars (QSOs) nearby in projection has the potential to provide strong constraints o…
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…
Galactic Rain: Cool Gas Inflows in Red Geyser Galaxies and Their Connection to AGN Activity and Interactions
Arian Moghni, Namrata Roy, Timothy M. Heckman +3
Red geysers are a population of massive (log[M/M]~10.5), quiescent galaxies that exhibit large-scale but weak, bi-symmetric ionized gas outflows, interpreted as signatures…
Barium Stars Across the Milky Way: Probing Their Origins via the GALAH Survey
Jaden Levine, Catherine Manea, Keith Hawkins +4
Barium stars are unusually enriched in barium ([Ba/Fe] >= 1.0 dex) and not predicted by current Galactic chemical evolution models. Previous observations of barium stars have found…
CLASSY XIII. Cutting through the Clouds - Comparing Indirect Tracers of Ionizing Photon Escape
Kaelee S. Parker, Danielle A. Berg, John Chisholm +25
The Epoch of Reionization (EoR) provides critical insights into the role of early galaxies in shaping the ionization state of the universe. However, because of the opacity of the i…
Ultra-strong MgII absorbers trace both inflowing and outflowing gas: insights from dual down-the-barrel and quasar sightlines
Antonia Fernández-Figueroa, Glenn G. Kacprzak, Tania M. Barone +4
We present Keck/LRIS spectroscopy of seven isolated galaxy-quasar pairs at , each exhibiting ultra-strong MgII absorption ( Å), probing both…
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…
Galactic Gas Flows from Halo to Disk: Tomography and Kinematics at the Milky Way's Disk-Halo Interface
Hannah V. Bish, Jessica K. Werk, J. Xavier Prochaska +4
We present a novel absorption line survey using 54 blue horizontal branch stars (BHBs) in the Milky Way halo as background sources for detecting gas flows at the disk-halo interfac…
The Nature of Ionized Gas in the Milky Way Galactic Fountain
Jessica K. Werk, Kate H. R. Rubin, Hannah V. Bish +6
We address the spatial scale, ionization structure, mass and metal content of gas at the Milky Way disk-halo interface detected as absorption in the foreground of seven closely-spa…
