The COS-Halos Survey: Rationale, Design, and A Census of Circumgalactic Neutral Hydrogen
Jason Tumlinson, Christopher Thom, Jessica Werk +11
We present the design and methods of the COS-Halos survey, a systematic investigation of the gaseous halos of 44 z = 0.15-0.35 galaxies using background QSOs observed with the Cosm…
Not Dead Yet: Cool Circumgalactic Gas in the Halos of Early Type Galaxies
Christopher Thom, Jason Tumlinson, Jessica K. Werk +10
We report new observations of circumgalactic gas in the halos of early type galaxies obtained by the COS-Halos Survey with the Cosmic Origins Spectrograph onboard the Hubble Space…
The COS-Dwarfs Survey: The Carbon Reservoir Around sub-L* Galaxies
Rongmon Bordoloi, Jason Tumlinson, Jessica K. Werk +12
We report new observations of circumgalactic gas from the COS-Dwarfs survey, a systematic investigation of the gaseous halos around 43 low-mass z 0.1 galaxies using backgrou…
A Catalogue of Field Horizontal Branch Stars Aligned with High Velocity Clouds
Christopher Thom, Brad K. Gibson, Norbert Christlieb
We present a catalogue of 430 Field Horizontal Branch (FHB) stars, selected from the Hamburg/ESO Survey (HES), which fortuitously align with high column density neutral hydrogen (H…
Is High-Velocity Cloud Complex C Associated with the Galactic Warp?
Daisuke Kawata, Christopher Thom, Brad K. Gibson
We test the hypothesis that High-Velocity gas cloud Complex C is actually a high-latitude spiral arm extension in the direction of the Galactic warp, as opposed to the standard int…
The COS/UVES Absorption Survey of the Magellanic Stream. III: Ionization, Total Mass, and Inflow Rate onto the Milky Way
Andrew J. Fox, Bart P. Wakker, Kathleen A. Barger +14
Dynamic interactions between the two Magellanic Clouds have flung large quantities of gas into the halo of the Milky Way, creating the Magellanic Stream, the Magellanic Bridge, and…
