Abstract
The intergalactic medium (IGM) is thought to have been highly ionized earlier than z ∼ 4 (Gunn & Peterson 1965; Schneider et al. 1989, 1991). However, the reionization history of the early universe has not been elucidated satisfactorily. Mainly because of the high density and possibly because of relatively weak ionizing radiation, the ionizing photons could not propagate freely at high redshifts even in linear density fluctuations, so that self-shielded neutral cores or shadowed low ionization regions could emerge. In this paper, we solve the 3D radiation transfer for UV photons in a clumpy universe, and explore the effects of cosmic reionization in detail.
