Interstellar and Circumgalactic Properties of an Unseen $z = 6.84$ Galaxy: Abundances, Ionization, and Heating in the Earliest Known Quasar Absorber

Robert A. Simcoe, Masafusa Onoue, Anna-Christina Eilers +5

We analyze relative abundances and ionization conditions in a strong absorption system at z=6.84, seen in the spectrum of the z=7.54 background quasar ULAS J134208.10+092838.61. Si…

The Cosmic Ultraviolet Baryon Survey (CUBS) II: Discovery of an H $_{2}$ -Bearing DLA in the Vicinity of an Early-Type Galaxy at z = 0.576

Erin Boettcher, Hsiao-Wen Chen, Fakhri S. Zahedy +18

We report the serendipitous detection of an H $_{2}$ -bearing damped Lyman- $α$ absorber at z = 0.576 in the spectrum of the QSO J0111-0316 in the Cosmic Ultraviolet Baryon Survey. Sp…
