Reionization, chemical enrichment and seed black holes from the first stars: is Population III important ?
RICOTTI M. and OSTRIKER J.P.
Abstract (from CDS):
We also develop a semi-analytic code to study how τeis sensitive to cosmological parameters, finding essentially the same results. Neglecting feedback effects, we find simple relationships for τeas a function of the power spectrum spectral index and the emission efficiency of ionizing radiation for cold dark matter and warm dark matter cosmologies. Surprisingly, we estimate that a warm dark matter scenario (with particle mass of 1.25 keV) reduces τeby only approximately 10 per cent.
