Probing the metallicity and ionization state of the circumgalactic medium at z~6 and beyond with OI absorption (2013)
Journal Article

Low-ionization metal absorption due to O I has been identified as an important probe of the physical state of the intergalactic/circumgalactic medium at the tail end of reionization. We use here high-resolution hydrodynamic simulations to interpret t... Read More about Probing the metallicity and ionization state of the circumgalactic medium at z~6 and beyond with OI absorption.

The one-dimensional Lyα forest power spectrum from BOSS (2013)
Journal Article

We have developed two independent methods for measuring the one-dimensional power spectrum of the transmitted flux in the Lyman-α forest. The first method is based on a Fourier transform and the second on a maximum-likelihood estimator. The two metho... Read More about The one-dimensional Lyα forest power spectrum from BOSS.

New measurements of the ionizing ultraviolet background over 2 < z < 5 and implications for hydrogen reionization (2013)
Journal Article

We present new measurements of the intensity of the ionizing ultraviolet background and the global emissivity of ionizing photons over 2 < z < 5. Our results are based on a suite of updated measurements of physical properties of the high-redshift int...

On the rapid demise of Lyman-alpha emitters at z>7 due to the increasing incidence of optically thick absorption systems (2013)
Journal Article

A variety of independent observational studies have now reported a significant decline in the fraction of Lyman-break galaxies which exhibit Ly-a emission over the redshift interval z=6-7. In combination with the strong damping wing extending redward...
