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…
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 <…
