PublicaciónA case study of hurdle and generalized additive models in astronomy: the escape of ionizing radiation
The dark ages of the Universe end with the formation of the first generation of stars residing in primeval galaxies. These objects were the first to produce...

PublicaciónAn ionized superbubble powered by a protocluster at z = 6.5
We show herein that a proto-cluster of Ly α emitting galaxies, spectroscopically confirmed at redshift 6.5, produces a remarkable number of ionizing continuum...

PublicaciónConditions for Reionizing the Universe with a Low Galaxy Ionizing Photon Escape Fraction
We explore scenarios for reionizing the intergalactic medium with low galaxy ionizing photon escape fractions. We combine simulation-based halo mass–dependent...

PublicaciónConstraining the Epoch of Reionization from the Observed Properties of the High-z Universe
We combine observational data on a dozen independent cosmic properties at high-z with the information on reionization drawn from the spectra of distant luminous...

PublicaciónDifferences and similarities of stellar populations in LAEs and LBGs at z ∼ 3.4-6.8
Lyman alpha emitters (LAEs) and Lyman break galaxies (LBGs) represent the most common groups of star-forming galaxies at high z, and the differences between...

PublicaciónGalactic wind X-ray heating of the intergalactic medium during the Epoch of Reionization
The diffuse soft X-ray emissivity from galactic winds is computed during the Epoch of Reionization (EoR). We consider two analytic models, a pressure-driven...
