Connecting CGM enrichment with Lyman alpha emitters at 2.9 < z < 6.7

A. M. Sebastian, E. Ryan-Weber, R. L. Davies +2

We present the results of a blind search for Lyman emitters (LAEs) in three deep archival quasar fields from VLT/MUSE using state-of-the-art detection algorithms. We e…

E-XQR-30: Evidence for an Increase in the Ionization State of Metal Absorbers from z~6 to z~2

Stephanie Rowlands, R. L. Davies, E. Ryan-Weber +15

We investigate the evolution of the ionization state of metal-enriched gas in and around galaxies near the epoch of reionization using a sample of 488 metal absorption systems at 4…

Evidence of Pop~III stars' chemical signature in neutral gas at z~6. A study based on the E-XQR-30 spectroscopic sample

Alessio Sodini, Valentina D'Odorico, Stefania Salvadori +16

This study explores the metal enrichment signatures attributed to the first generation of stars (PopIII) in the Universe, focusing on the E-XQR-30 sample. We aim to identify traces…

E-XQR-30: The evolution of MgII, CII and OI across 2<z<6

Alma Maria Sebastian, Emma Ryan-Weber, Rebecca L. Davies +12

Intervening metal absorbers in quasar spectra at can be used as probes to study the chemical enrichment of the Universe during the Epoch of Reionization (EoR). This work pr…

The XQR-30 Metal Absorber Catalog: 778 Absorption Systems Spanning 2 < z < 6.5

Rebecca L. Davies, Emma Ryan-Weber, Valentina D'Odorico +11

Intervening metal absorption lines in the spectra of z > 6 quasars are fundamental probes of the ionization state and chemical composition of circumgalactic and intergalactic gas n…
