Abstract: (arXiv)

If most of the dark matter in the Universe is composed of WIMPs, their annihilation will release energy, ionizing some of the gas in the Universe. We investigate the effect of the earliest dark matter halos on reionization. It is shown that these halos could contribute significantly to the WMAP inferred optical depth. Our results may be combined with studies of other ionizing sources to put stronger constraints on the allowed halo and particle parameters.
