The First Observations of Low-Redshift Damped Lyman-α Systems with the Cosmic Origins Spectrograph: Chemical Abundances and Affiliated Galaxies
A. J. Battisti, J. D. Meiring, T. M. Tripp +6
We present Cosmic Origins Spectrograph (COS) measurements of metal abundances in eight 0.083<z<0.321 damped Lyman-α(DLA) and sub-damped Ly-α absorption systems serendipitously di…
The Gas-Galaxy Connection at z = 0.35: OVI and HI Absorption Towards J0943+0531
C. Thom, J. K. Werk, J. Tumlinson +4
We present observations of HI and OVI absorption systems proximate to a galaxy at z_gal = 0.3529. The absorption was detected serendipitously in Cosmic Origins Spectrograph observa…
The stellar content of the Hamburg/ESO survey. III. Field horizontal-branch stars in the Galaxy
N. Christlieb, T. C. Beers, C. Thom +5
We present a sample of 8321 candidate Field Horizontal-Branch (FHB) stars selected by automatic spectral classification in the digital data base of the Hamburg/ESO objective-prism…
The Bimodal Metallicity Distribution of the Cool Circumgalactic Medium at z<1
N. Lehner, J. C. Howk, T. M. Tripp +7
We assess the metal content of the cool (10^4 K) circumgalactic medium (CGM) about galaxies at z<1 using an H I-selected sample of 28 Lyman limit systems (LLS, defined here as abso…
Bright Metal-Poor Stars from the Hamburg/ESO Survey. I. Selection and Follow-up Observations from 329 Fields
A. Frebel, N. Christlieb, J. E. Norris +9
We present a sample of 1777 bright (9<B<14) metal-poor candidates selected from the Hamburg/ESO Survey (HES). Despite saturation effects present in the red portion of the HES objec…
How do Galaxies Accrete Gas and Form Stars?
M. E. Putman, P. Henning, A. Bolatto +42
Great strides have been made in the last two decades in determining how galaxies evolve from their initial dark matter seeds to the complex structures we observe at z=0. The role o…
