A dense, metal-rich absorber driven by a heavily dust-obscured galaxy: The direct evidence of CGM enrichment at
Qinyue Fei, Seiji Fujimoto, Gabriel Brammer +23
We report the serendipitous discovery of a dense, metal-enriched circumgalactic medium (CGM) absorber at z=7.03, together with its host galaxy, identified along the sightline towar…
First-star imprints in a metal-poor galaxy overdensity near the end of reionization
Zihao Li, Koki Kakiichi, Lise Christensen +24
The first generation of stars, known as Population III (Pop III), formed from primordial gas consisting solely of hydrogen and helium and is believed to have emerged only a few hun…
The Qz5 Survey (II): Metallicity Evolution of Damped Lyα Systems Out to z5
Marie Wisz, Marc Rafelski, Grecco Oyarzun +10
Damped Ly absorbers (DLAs) are the highest \HI\ column density (\NHI) absorption line systems detected in the spectra of background quasars. DLAs dominate the neutral gas conten…
Unmixed metals: Variations in the enrichment of z~4 sub-damped Lyman alpha systems
Trystyn A. M. Berg, Louise A. Welsh, Ryan J. Cooke +4
The chemical abundance patterns of near-pristine objects provide important constraints on the properties of the first generations of stars in the Universe. We present the chemical…
The Qz5 Survey (I): How the HI Mass Density of the Universe Evolves With Cosmic Time
Grecco A. Oyarzún, Marc Rafelski, Lise Christensen +9
We report that the neutral hydrogen (HI) mass density of the Universe () increases with cosmic time since , peaks at , and then decreases toward $z \sim…
Galaxy Formation and Symbiotic Evolution with the Inter-Galactic Medium in the Age of ELT-ANDES
Valentina D'Odorico, James S. Bolton, Lise Christensen +21
High-resolution absorption spectroscopy toward bright background sources has had a paramount role in understanding early galaxy formation, the evolution of the intergalactic medium…
