The Red Dead Redemption Survey of Circumgalactic Gas About Massive Galaxies. I. Mass and Metallicity of the Cool Phase
Michelle A. Berg, J. Christopher Howk, Nicolas Lehner +6
We present a search for HI in the circumgalactic medium (CGM) of 21 massive (), luminous red galaxies (LRGs) at . Using UV spectro…
The COS Absorption Survey of Baryon Harbors (CASBaH): Warm-hot Circumgalactic Gas Reservoirs Traced by Ne VIII Absorption
Joseph N. Burchett, Todd M. Tripp, J. Xavier Prochaska +13
We survey the highly ionized circumgalactic media (CGM) of 29 blindly selected galaxies at 0.49 < z_(gal) < 1.44 based on high-S/N ultraviolet spectra of z > 1 QSOs and the galaxy…
New constraints on the nature and origin of the Leading Arm of the Magellanic Stream
P. Richter, A. J. Fox, B. P. Wakker +5
We present a new precision measurement of gas-phase abundances of S, O, N, Si, Fe, P, Al, Ca as well as molecular hydrogen (H_2) in the Leading Arm (region II, LAII) of the Magella…
The COS CGM Compendium (CCC). I: Survey Design and Initial Results
Nicolas Lehner, Christopher B. Wotta, J. Christopher Howk +3
We present a neutral hydrogen-selected absorption-line survey of gas with HI column densities 15<log N(HI)<19 at z<1 using the Cosmic Origins Spectrograph on the Hubble Space Teles…
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…
Chemical Abundances in the Leading Arm of the Magellanic Stream
Andrew J. Fox, Kathleen A. Barger, Bart P. Wakker +8
The Leading Arm (LA) of the Magellanic Stream is a vast debris field of H I clouds connecting the Milky Way and the Magellanic Clouds. It represents an example of active gas accret…
