Nearly pristine gas in a galaxy 1 billion years after the Big Bang
Sarah E. I. Bosman, Frederick B. Davies, Louise Welsh +22
Excitation of carbon and oxygen ions is the primary mechanism by which collapsing gas clouds dissipate heat to form new stars. At early cosmic times, in galaxies with chemically pr…
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…
Damping Wing-Like Features in the Stacked Ly Forest: Potential Neutral Hydrogen Islands at
Yongda Zhu, George D. Becker, Sarah E. I. Bosman +28
Recent quasar absorption line observations suggest that reionization may end as late as . As a means to search for large neutral hydrogen islands at , we revisi…
Constraints on the Evolution of the Ionizing Background and Ionizing Photon Mean Free Path at the End of Reionization
Frederick B. Davies, Sarah E. I. Bosman, Prakash Gaikwad +16
The variations in Ly forest opacity observed at between lines of sight to different background quasars are too strong to be caused by fluctuations in the density field a…
Searching for [CII] Emission from the First Sample of OI Absorption-Associated Galaxies with ALMA
Yunjing Wu, Zheng Cai, Jianan Li +13
We report the first statistical analyses of [CII] and dust continuum observations in six strong OI absorber fields at the end of the reionization epoch obtained by the Atacama Larg…
