OzSSy1: The Australian Southern Seyfert-1 Spectroscopic Atlas and Catalogue at z < 0.1
Neelesh Amrutha, Christian Wolf, Christopher A. Onken +3
We present a spectroscopic atlas of 887 broad-line active galactic nuclei (AGNs) in the Southern sky, spanning redshifts , declinations deg and Galactic latitudes…
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…
Percent-level timing of reionization: self-consistent, implicit-likelihood inference from XQR-30+ Ly forest data
Yuxiang Qin, Andrei Mesinger, David PrelogoviÄ +13
The Lyman alpha (Lya) forest in the spectra of z>5 quasars provides a powerful probe of the late stages of the Epoch of Reionization (EoR). With the recent advent of exquisite data…
