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 ...

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 ...

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.

The mean free path of hydrogen ionizing photons during the epoch of reionization [PDF]

, 2017
We use the Aurora radiation-hydrodynamical simulations to study the mean free path (MFP) for hydrogen ionizing photons during the epoch of reionization. We directly measure the MFP by averaging the distance 1 Ry photons travel before reaching an optical ...

Detecting the signature of helium reionization through 3HeII 3.46 cm line-intensity mapping

Astronomy & Astrophysics
Context. Helium reionization is the most recent phase change of the intergalactic medium, yet its timing and main drivers remain uncertain. Among the probes to trace to trace how it unfolds, the 3.46 cm hyperfine line of singly ionized helium has opened ...

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 ...

Constraining reionization using 21 cm observations in combination with CMB and Lyman-alpha forest data

, 2009
In this paper, we explore the constraints on the reionization history that are provided by current observations of the Lyman-alpha forest and the CMB.

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.
