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…
