The Universe Was Reionized Twice
With a top-heavy initial stellar mass function for Population III stars, as recent simulations seem to suggest, we show that Pop III stars can, for the first time, reionize the universe at z ∼ 15 − 20 in the standard cold dark matter cosmological model. The physical reason rests in the positive feedback from Pop III star formation, made possible by a high X-ray background, which, in turn, is pr...
متن کاملWas the Universe Reionized by Massive Population-iii Stars?
The WMAP satellite has measured a large optical depth to electron scattering after cosmological recombination of τes = 0.17 ± 0.04, implying significant reionization of the primordial gas only ∼ 200 million years after the big bang. However, the most recent overlap of intergalactic HII regions must have occurred at z . 9 based on the Lyα forest constraint on the thermal history of the intergala...

متن کاملDid the Universe Reionize at Redshift Six?
In light of recent observations of quasar spectra by Becker et al. (2001) and Djorgovski et al. (2001), we study the observational signatures of different stages of the reionization epoch. During the initial, pre-overlap stage, the hydrogen throughout the universe is neutral except for isolated H II bubbles due to individual ionizing sources. The central stage of reionization is the overlap sta...
متن کاملSecondary CMB anisotropies in a universe reionized in patches
In a universe reionized in patches, the Doppler effect from Thomson scattering off free electrons generates secondary cosmic microwave background (CMB) anisotropies. For a simple model with small patches and late reionization, we analytically calculate the anisotropy power spectrum. Patchy reionization can, in principle, be the main source of anisotropies on arcminute scales. On larger angular ...
