On the Detectability of the Hydrogen 3-cm Fine Structure Line from the EoR
Mark Dijkstra, Adam Lidz, Jonathan R. Pritchard +4
A soft ultraviolet radiation field, 10.2 eV < E <13.6 eV, that permeates neutral intergalactic gas during the Epoch of Reionization (EoR) excites the 2p (directly) and 2s (indirect…
Constraining massive neutrinos using cosmological 21 cm observations
Jonathan R. Pritchard, Elena Pierpaoli
Observations of neutrino oscillations show that neutrinos have mass. However, the best constraints on this mass currently come from cosmology, via measurements of the cosmic microw…
Evolution of the 21 cm signal throughout cosmic history
Jonathan R. Pritchard, Abraham Loeb
The potential use of the redshifted 21 cm line from neutral hydrogen for probing the epoch of reionization is motivating the construction of several low-frequency interferometers.…
Cosmic Reionization and the 21-cm signal: Comparison between an analytical model and a simulation
Mario G. Santos, Alexandre Amblard, Jonathan Pritchard +3
We measure several properties of the reionization process and the corresponding low-frequency 21-cm signal associated with the neutral hydrogen distribution, using a large volume,…
21 cm fluctuations from inhomogeneous X-ray heating before reionization
Jonathan R. Pritchard, Steven R. Furlanetto
Many models of early structure formation predict a period of heating immediately preceding reionization, when X-rays raise the gas temperature above that of the cosmic microwave ba…
The Scattering of Lyman-series Photons in the Intergalactic Medium
Steven Furlanetto, Jonathan R. Pritchard
We re-examine scattering of photons near the Lyman-alpha resonance in the intergalactic medium (IGM). We first derive a general integral solution for the radiation field around res…
