Quasar Impostors: Two Extremely UV-Bright () Reionisation-Epoch Galaxies Powered by Very Massive Stars
Daming Yang, Joseph F. Hennawi, Sarah E. I. Bosman +20
The extreme bright end of the galaxy UV luminosity function during reionisation remains poorly constrained, particularly where the galaxy and quasar luminosity functions overlap an…

First constraints on the local ionization topology in front of two quasars at z ~ 7.5
Timo Kist, Joseph F. Hennawi, Frederick B. Davies +10
Thus far, Lyman- damping wings towards quasars have been used to probe the \textit{global} ionization state of the foreground intergalactic medium (IGM). A new parameterization…

A local, topology-independent parameterization of quasar IGM damping wings
Timo Kist, Joseph F. Hennawi, Frederick B. Davies
Lyman- damping wings towards quasars provide a unique probe of reionization because their strength correlates strongly with the global volume-averaged neutral hydrogen (HI) frac…
