We determine the thermal evolution of the intergalactic medium (IGM) over 3 Gyr of cosmic time 1.8< z< 5.4 by comparing measurements of the Lyα forest power spectrum to a suite of ̃70 hydrodynamical simulations. We conduct Bayesian inference of IGM

We decompose the Lyman-α (Lyα) forest of an extensive sample of 75 high signal-to-noise ratio and high-resolution quasar spectra into a collection of Voigt profiles. Absorbers located near caustics in the peculiar velocity field have the smallest D

During reionization, neutral hydrogen in the intergalactic medium (IGM) imprints a damping wing absorption feature on the spectrum of high-redshift quasars. A detection of this signature provides compelling evidence for a significantly neutral Univer

The He ii transverse proximity effect - enhanced He ii Lyα transmission in a background sightline caused by the ionizing radiation of a foreground quasar - offers a unique opportunity to probe the emission properties of quasars, in particular the em

The amplitude of the ionizing background that pervades the intergalactic medium (IGM) at the end of the epoch of reionization provides a valuable constraint on the emissivity of the sources that reionized the universe. While measurements of the ioniz
