  • We simulate a plausible cosmological model in considerable physical and numerical detail through the successive phases of reheating (at 10 z 20) and reionization at z ≈ 7. We assume an efficiency of high-mass star formation appropriate to leave the universe, after it becomes transparent, with an ionizing background J21 ≈ 0.4 (at z = 4), near (and perhaps slightly below) the observed value. Since the same stars produce the ionizing radiation and the first generation of heavy elements, a mean… CONTINUE READING
