Tracing the sources of reionization in cosmological radiation hydrodynamics simulations
Résumé
We use the photon flux and absorption tracer algorithm presented in Katz et al. to characterize the contribution of haloes of different mass and stars of different age and metallicity to the reionization of the Universe. We employ a suite of cosmological multifrequency radiation hydrodynamics AMR simulations that are carefully calibrated to reproduce a realistic reionization history and galaxy properties at z ≥ 6. In our simulations, haloes with mass 109M⊙h−1
