HST UV Spectroscopy of the Dwarf Starburst Galaxy Pox 186
The Astrophysical Journal, 2023 Studying the galaxies responsible for reionization is often conducted through local reionization-era analogs; however, many of these local analogs are too massive to be representative of the low-mass star-forming galaxies that are thought to play a ...

High resolution simulations of the reionization of an isolated Milky Way - M31 galaxy pair [PDF]
, 2013 We present the results of a set of numerical simulations aimed at studying reionization at galactic scale. We use a high resolution simulation of the formation of the Milky Way-M31 system to simulate the reionization of the local group.

Impact of general reionization scenarios on extraction of inflationary parameters [PDF]
, 2010 Determination of whether the Harrison--Zel'dovich spectrum for primordial scalar perturbations is consistent with observations is sensitive to assumptions about the reionization scenario.

Detecting Helium Reionization with Fast Radio Bursts
, 2020 Fast radio bursts (FRB) probe the electron density of the universe along the path of propagation, making high redshift FRB sensitive to the helium reionization epoch.

Reionization and Beyond: detecting the peaks of the cosmological 21cm signal [PDF]
, 2014 [ABRIDGED] The cosmological 21cm signal is set to become the most powerful probe of the early Universe, with first generation interferometers aiming to make statistical detections of reionization. There is increasing interest also in the pre-reionization

The Astrophysical Journal, 2023 We report the most sensitive upper limits to date on the 21 cm epoch of reionization power spectrum using 94 nights of observing with Phase I of the Hydrogen Epoch of Reionization Array (HERA).

The Universe is at Most 88% Neutral at z = 10.6
The Astrophysical Journal Letters, 2023 Recent observations of GN-z11 with JWST have revealed a Ly α emission line with an equivalent width (EW) of 18 ± 2 Å. At z = 10.6, this galaxy is expected to lie in the heart of reionization.

Simulating Reionization: Character and Observability [PDF]
, 2007 In recent years there has been considerable progress in our understanding of the nature and properties of the reionization process. In particular, the numerical simulations of this epoch have made a qualitative leap forward, reaching sufficiently large ...

Cosmic reionization constraints on the nature of cosmological perturbations [PDF]
, 2006 We study the reionization history of the Universe in cosmological models with non-Gaussian density fluctuations, taking them to have a renormalized $\chi^2$ probability distribution function parametrized by the number of degrees of freedom, $\nu$.

Reionization Histories of Milky Way Mass Halos
, 2013 We investigate the connection between the epoch of reionization and the present day universe, by examining the extended mass reionization histories of dark matter halos identified at z=0.
