Forest without Trees is still Fruitful: Constraints on the thermal state of the neutral IGM at with the 21-cm forest power spectrum
Tomáš Šoltinský, 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 emitters (LAEs) in three deep archival 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…
Updated dark pixel fraction constraints on reionization's end from the Lyman-series forests of XQR-30
Frederick B. Davies, Sarah E. I. Bosman, Valentina D'Odorico +16
The fraction of "dark pixels" in the Ly and other Lyman-series forests at provides a powerful constraint on the end of the reionization process. Any spectral region…
The clustering of C IV and Si IV at the end of reionisation: A perspective from the E-XQR-30 survey
Louise Welsh, Valentina D'Odorico, Fabio Fontanot +14
We aim to study the clustering of metal absorption lines and the structures that they arise in as a function of cosmic time. We focus on C IV and Si IV absorption features that are…
An extremely metal-poor Lyman emitter candidate at revealed through absorption spectroscopy
Dominika ÄurovÄÃková, Anna-Christina Eilers, Robert A. Simcoe +10
We report the discovery of a Lyman emitter (LAE) candidate in the immediate foreground of the quasar PSO J158-14 at at a projected distance $\sim29\ {\rm…
