Forest without Trees is still Fruitful: Constraints on the thermal state of the neutral IGM at $z \approx 5.6$ with the 21-cm forest power spectrum

TomÃ¡Å¡ Å oltinskÃ½, Arnab Chakraborty, Girish Kulkarni +10

Neutral regions of the intergalactic medium (IGM) during the Epoch of Reionization (EoR) remain largely unexplored due to the limitations of existing probes. Owing to discoveries o…

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 $I^\pm$ emitters (LAEs) in three deep archival $z \sim 6$ quasar fields from VLT/MUSE using state-of-the-art detection algorithms. We…

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…
