High-S/N Quasar Observations with HST/COS: Deep Fields for Spectroscopy
Andrew J. Fox, Jerry Kriss, Philipp Richter +49
Hubble is still in prime observing condition for making transformative discoveries in UV astronomy. In this white paper we describe the science case for a deep (S/N>30) UV spectros…
MUSEQuBES: Investigating the Physical and Chemical Properties of Circumgalactic Gas Around Ly Emitters at
Eshita Banerjee, Sowgat Muzahid, Joop Schaye +2
We present a detailed study of the physical properties of absorbers associated with \lya\ emitters (LAEs) from the MUSEQuBES survey. Using \HI\ and ionic column densi…
MUSEQuBES: Physical conditions, origins, and multi-element abundances of the circumgalactic medium of an isolated, star-forming dwarf galaxy at z=0.57
Sean D. Johnson, Nishant Mishra, Sowgat Muzahid +13
In dwarf galaxy models, outflows expel metal-enriched interstellar medium (ISM) into the circumgalactic medium (CGM) to reproduce their observed low metallicities, but measurements…
MUSEQuBES: The Column Density, Covering Fraction, Mass, and Environmental Dependence of Cool HI Gas Around Low-Redshift Galaxies
Sayak Dutta, Sowgat Muzahid, Joop Schaye +6
We investigate cool HI gas traced by Lyman series absorption around 256 galaxies at z ~ 0.48 (median stellar mass, log10(M*/Msun) = 8.7) using 15 background quasars (median impact…
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…
MUSEQuBES: Connecting HI absorption with Ly emitters at
Eshita Banerjee, Sowgat Muzahid, Joop Schaye +6
We present a comprehensive analysis of HI absorption around 96 lya emitters (LAEs) at (median lya luminosity erg.s). These LAEs were identifie…
