Lyα emission-line reconstruction for high-z QSOs
We introduce an intrinsic Ly\alpha\ emission line profile reconstruction method for high-$z$ quasars (QSOs). This approach utilises a covariance matrix of emission line properties obtained from aExpand
21CMMC: an MCMC analysis tool enabling astrophysical parameter studies of the cosmic 21 cm signal
We introduce 21CMMC: a parallelized, Monte Carlo Markov Chain analysis tool, incorporating the epoch of reionization (EoR) seminumerical simulation 21CMFAST. 21CMMC estimates astrophysical parameterExpand
The global history of reionization
Using a Bayesian framework, we quantify what current observations imply about the history of the epoch of reionisation (EoR). We use a popular, three-parameter EoR model, flexible enough toExpand
Are we witnessing the epoch of reionisation at $z=7.1$ from the spectrum of J1120+0641?
We quantify the presence of Ly\alpha\ damping wing absorption from a partially-neutral intergalactic medium (IGM) in the spectrum of the $z=7.08$ QSO, ULASJ1120+0641. Using a Bayesian framework, weExpand
Constraints on reionization from the z = 7.5 QSO ULASJ1342+0928
The recent detection of ULASJ1342+0928, a bright QSO at $z=7.54$, provides a powerful probe of the ionisation state of the intervening intergalactic medium, potentially allowing us to set strongExpand
Quasar UV luminosity function evolution up to z = 8
We study the redshift evolution of the quasar UV Luminosity Function (LF) for 0.5 6 quasars detectable by ongoing and future NIR surveys (as EUCLID and WFIRST), and (ii) number counts for a singleExpand
Improving the Epoch of Reionization Power Spectrum Results from Murchison Widefield Array Season 1 Observations
Measurements of 21 cm Epoch of Reionization (EoR) structure are subject to systematics originating from both the analysis and the observation conditions. Using 2013 data from the Murchison WidefieldExpand
Emulating Simulations of Cosmic Dawn for 21 cm Power Spectrum Constraints on Cosmology, Reionization, and X-Ray Heating
Draft version May 16, 2017 Preprint typeset using L A TEX style AASTeX6 v. 1.0 EMULATING SIMULATIONS OF COSMIC DAWN FOR 21 cm POWER SPECTRUM CONSTRAINTS ON COSMOLOGY, REIONIZATION, AND X-RAY HEATINGExpand
Deep multiredshift limits on Epoch of Reionization 21 cm power spectra from four seasons of Murchison Widefield Array observations
Abstract We compute the spherically averaged power spectrum from four seasons of data obtained for the Epoch of Reionization (EoR) project observed with the Murchison Widefield Array (MWA). WeExpand
