Abstract
In hierarchical models of structure formation, an early cosmic UV background (UVB) is produced by the small (math formular) halos that collapse before cosmological reionization. If the first collapsed halos harbor stars, then their UV flux below 13.6 eV photo-dissociates the molecular hydrogen H2 in subsequently collapsing halos within a large sphere of influence. This causes a pause in the cosmic star-formation history: the buildup of the UVB and the epoch of reionization are delayed until larger halos ( math formular) collapse. In contrast, if the small halos harbor mini-quasars with hard spectra extending to -1keV, 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.
