Abstract
In hierarchical models of structure formation, an early cosmic UV background (UVB) is produced by the small (T vir ≲ 10^4K) halos that collapse before cosmological reionization. If the sources in the first collapsed halos are stars, then their UV flux below 13.6 eV photo-dissociates the molecular hydrogen H2in subsequently collapsing halos and causes a pause in the cosmic star-formation history. The buildup of the UVB, and reionization is delayed until larger halos (T vir ≳ 10^4K)collapse. In contrast, if the small halos host mini-quasars with hard spectra extending to ~ 1 keV, then their X-rays balance the effects of the UVB, the negative feedback does not occur, and reionization can be caused early on by the small halos.
