Inhomogeneous reionization regulated by radiative and stellar feedbacks

Abstract I present the results of a study of the IGM reionization due to an inhomogeneous distribution of stellar sources, which takes into account a self-consistent treatment of both radiative (i.e. ionizing and H2-photodissociating photons) and stellar (i.e. SN explosions) feedbacks regulated by massive stars. This allows one to describe the topology of the ionized and dissociated regions in various cosmic epochs and derive the time evolution of the H and H2 filling factor, the star formation rate and final fate of objects.
