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.

What Next-Generation 21 cm Power Spectrum Measurements Can Teach Us About the Epoch of Reionization [PDF]
, 2013 A number of experiments are currently working towards a measurement of the 21 cm signal from the Epoch of Reionization. Whether or not these experiments deliver a detection of cosmological emission, their limited sensitivity will prevent them from ...

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.

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.

Studying Reionization with Ly-alpha Emitters
, 2007 We show that observations of high-redshift Ly-alpha emitters (LAEs) have the potential to provide definitive evidence for reionization in the near future.

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

Reionization in Technicolor [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We present the Technicolor Dawn simulations, a suite of cosmological radiation-hydrodynamic simulations of the first 1.2 billion years. By modeling a spatially-inhomogeneous UVB on-the-fly with 24 frequencies and resolving dark matter halos down to $10^8 M_\odot$ within 12 $h^{-1}$ Mpc volumes, our simulations unify observations of the intergalactic ...

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).

Observational Constraints on Cosmic Reionization [PDF]
Annual Review of Astronomy and Astrophysics, 2006 Observations have set the first constraints on the epoch of reionization (EoR), corresponding to the formation epoch of the first luminous objects. Studies of Gunn-Peterson (GP) absorption indicate a rapid increase in the neutral fraction of the intergalactic medium (IGM) from xHI< 10−4at z ≤ 5.5, to xHI> 10−3, perhaps up to 0.1, at z∼6, while ...
