Abstrakt:

One of the possible sources of an anisotropy in the power spectrum of 21 cm brightness ﬂuctuations from the epoch of reionization is the delay in light traveltime along the line-of-sight. We examine the anisotropy between the parallel and transverse directions with respect to the line-of-sight with the LICORICE code. Based on Barkana & Loeb (2006) approach we study the time-delay eﬀect in the realistic numerical simulations of the epoch of reionization.
