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…
Inferring local quasar IGM damping wing constraints
Timo Kist, Joseph F. Hennawi, Frederick B. Davies
Lyman- damping wings towards quasars are a highly sensitive probe of the neutral hydrogen (HI) content in the foreground intergalactic medium (IGM), not only constraining the gl…
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…
Quantifying the Precision of IGM Damping Wing Measurements Towards Quasars
Timo Kist, Joseph F. Hennawi, Frederick B. Davies
We investigate the precision with which the Lyman- damping wing signature imprinted on the spectra of high-redshift quasars (QSOs) by the foreground neutral intergalactic medium…
Precisely Measuring the Cosmic Reionization History from IGM Damping Wings Towards Quasars
Joseph F. Hennawi, Timo Kist, Frederick B. Davies +1
We introduce a new approach for analyzing the IGM damping wings imprinted on the proximity zones of quasars in the epoch of reionization (EoR). Whereas past work has typically forg…
