A Giant Intragroup Nebula Hosting a Damped Lya Absorber at z=0.313
Hsiao-Wen Chen, Erin Boettcher, Sean D. Johnson +5
This paper reports the discovery of spatially-extended line-emitting nebula, reaching to ~100 physical kpc (pkpc) from a damped Lyα absorber (DLA) at z_DLA=0.313 along the sightlin…
The COS CGM Compendium. III: Metallicity and Physical Properties of the Cool Circumgalactic Medium at z<1
Nicolas Lehner, Christopher B. Wotta, J. Christopher Howk +3
We characterize the metallicities and physical properties of cool, photoionized gas in a sample of 152 z<1 strong Lya forest systems (SLFSs, absorbers with 15<log N(HI)<16.2). The…
Heavy Element Absorption Systems at : Metal-Poor Neutral Gas and a Diminishing Signature of Highly Ionized Circumgalactic Matter
T. J. Cooper, R. A. Simcoe, K. L. Cooksey +5
Ratios of different ions of the same element encode ionization information independently from relative abundances in quasar absorption line systems, crucial for understanding the m…
