Probing Direct Contributions of Galaxies and AGN to Cosmic Reionization in a Quasar Field J0226+0302 with JWST NIRCam and NIRSpec
Xiangyu Jin, Jinyi Yang, Feige Wang +19
We present JWST Cycle 2 NIRCam and NIRSpec observations in a quasar field J0226+0302 at z=6.5412 to probe the direct connections between the intergalactic medium (IGM), galaxies, a…
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…
Ly Emission from [OIII] Emitters Near Reionization: The role of environment in galaxy Ly detection
Seyedazim Hashemi, George D. Becker, Yongda Zhu +1
Using galaxy Ly emission to probe reionization relies on establishing baseline expectations for its detectability in the absence of attenuation by neutral gas in the IGM. Towar…
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…
