Three-dimensional simulation that models the transition from Population III to Population I/II star formation on cosmological scales. The physical model includes ionizing radiation from various stellar populations, and the mechanical energy input and chemical enrichment from SNe. The columns denote the redshift, and the rows the mass density, temperature, and metallicity originating from Population III and Population I/II stars, respectively. The box size is 1 Mpc (comoving). Star formation takes place in halos with masses between ≃106 and \({\simeq}10^{9}\mbox { M}_{\odot}\), and gradually enriches the IGM with metals. Adapted from Wise et al. (2012).
