An HST/COS legacy survey of high-velocity ultraviolet absorption in the Milky Way's circumgalactic medium and the Local Group
P. Richter, S. E. Nuza, A. J. Fox +9
To characterize the absorption properties of this circumgalactic medium (CGM) and its relation to the LG we present the so-far largest survey of metal absorption in Galactic high-v…
Low-metallicity Absorbers Account for Half of the Dense Circumgalactic Gas at z < 1
Christopher B. Wotta, Nicolas Lehner, J. Christopher Howk +2
We present an analysis of the metallicity distribution of the dense circumgalactic medium (CGM) of galaxies at 0.1 < z < 1.1 as probed by partial Lyman limit systems (pLLSs, 16.1 <…
The Cosmic Evolution of the Metallicity Distribution of Ionized Gas Traced by Lyman Limit Systems
Nicolas Lehner, John M. O'Meara, J. Christopher Howk +2
We present the first results from our KODIAQ Z survey aimed to determine the metallicity distribution and physical properties of the z>2 partial and full Lyman limit systems (pLLSs…
New Gapless COS G140L Mode Proposed for Background-Limited Far-UV Observations
Keith Redwine, Stephan R. McCandliss, Brian Fleming +6
Here we describe the observation and calibration procedure for a new G140L observing mode for the Cosmic Origins Spectrograph (COS) aboard the Hubble Space Telescope (HST). This mo…
The HI Content of the Universe over the Past 10 Gyrs
Marcel Neeleman, J. Xavier Prochaska, Joseph Ribaudo +4
We use the Hubble Space Telescope (HST) archive of ultraviolet (UV) quasar spectroscopy to conduct the first blind survey for damped Ly-alpha absorbers (DLAs) at low redshift (z <…
