Constraints on X-ray Emissions from the Reionization Era

, 2012
We examine the constraints on soft X-ray emissions from the reionization era. It has generally been assumed that the Universe was reionized by ultraviolet photons from massive stars.

Cosmic Reionization on Computers: The Evolution of the Ionizing Background and Mean Free Path

The Astrophysical Journal
Observations of the end stages of reionization indicate that at z  ≈ 5–6, the ionizing background is not uniform and the mean free path (MFP) changes drastically.

Reionization on ice

, 2006
The case for substantial far infrared ice emission in local ultraluminous infrared galaxies, expected based on the presence of mid-infrared ice absorption in their spectra and the known far infrared optical properties of ice, is still largely unsupported by direct observation owing to insufficient far infrared spectral coverage.

LIMFAST. III. Timing Cosmic Reionization with the 21 cm and Near-infrared Backgrounds

The Astrophysical Journal
The timeline of cosmic reionization remains uncertain despite sustained efforts to study how the ionizing output of early galaxies shaped the intergalactic medium (IGM).

Revised Active Galactic Nuclei Spectral Model Reveals a More Significant Role in Cosmic Reionization

The Astrophysical Journal Letters
Reionization marks one of the most important phase transitions in the history of the Universe, during which neutral baryonic matter was transformed into ionized plasma.

Efficient modeling of Lyman-α opacity fluctuations during the late reionization epoch

Astronomy & Astrophysics
The Lyman-α forest opacity fluctuations observed from high-redshift quasar spectra have been proven to be extremely successful in probing the late phase of the reionization epoch.

Observing the Epoch of Reionization with the Cosmic Microwave Background

, 2015
We review the observable consequences of the epoch of reionization (EoR) on the cosmic microwave background (CMB), and the resulting constraints on the EoR.

Reionization Parameter Inference from 3D Minkowski Functionals of the 21 cm Signals

The Astrophysical Journal
The Minkowski functionals (MFs), a set of topological summary statistics, have emerged as a powerful tool for extracting non-Gaussian information.
