We reconsider the problem of the cosmological reionization due to stellar sources and we focus our analysis on the basic parameters, such as stellar models and spectra, adopted for estimating the production rate of ionizing photons. In particular, we find that using zero metallicity models instead of the very metal poor ones, commonly adopted, significantly modifies the reionization epoch.

Abstract
We reconsider the problem of the cosmological reionization due to stellar sources and we focus our analysis on the basic parameters, such as stellar models and spectra, adopted for estimating the production rate of ionizing photons. In particular, we find that using zero metallicity models instead of the very metal poor ones, commonly adopted, significantly modifies the reionization epoch.
