A Galaxy Redshift Survey near HST/COS AGN Sight Lines
Brian A. Keeney, John T. Stocke, Cameron T. Pratt +8
To establish the connection between galaxies and UV-detected absorption systems in the local universe, a deep () and wide ( radius) galaxy redshift survey…
Probing the Southern Fermi Bubble in Ultraviolet Absorption using Distant AGNs
Md Tanveer Karim, Andrew J. Fox, Edward B. Jenkins +7
The Fermi Bubbles are two giant gamma-ray emitting lobes extending 55 above and below the Galactic Center. While the Northern Bubble has been extensively studied in ultra…
Extraplanar H II Regions in Spiral Galaxies. II. In Situ Star Formation in the Interstellar Thick Disk of NGC 4013
J. Christopher Howk, Katherine M. Rueff, Nicolas Lehner +3
We present observations of an H emitting knot in the thick disk of NGC 4013, demonstrating it is an H II region surrounding a cluster of young hot stars pc above the p…
Detection of Low Metallicity Warm Plasma in a Galaxy Overdensity Environment at z ~ 0.2
Anand Narayanan, Blair D. Savage, Preetish K. Mishra +3
We present results from the analysis of a multiphase O VI - broad Ly-alpha absorber at z = 0.19236 in the HST/COS spectrum of PG 1121+422. The low and intermediate ionization metal…
