One of the most promising ways to study the epoch of reionization (EoR) is through radio ob-servations of the redshifted 21-cm line emission from neutral hydrogen. These observations are complicated by the fact that the mapping of redshifts to line-of-sight positions is distorted by the peculiar velocities of the gas. Such distortions can be a source of error if they are not properly understood, but they also encode information about cosmology and astrophysics.
Jensen et al. (Mon,) studied this question.
