Cosmic reionization is one of the last major milestones in the evolution of the Universe. In roughly one billion years, the bulk of the hydrogen in the Universe is fully ionized by the radiation produced by early galaxies and quasars. While significant progress has been made in the recent years, completing the census of these ionizing sources is still a major challenge on both the observational and theoretical sides.
In this talk, I will discuss how radiation hydrodynamical simulations can be used to study the properties of the first galaxies and AGN with a particular focus on their relative role in reionizing the Universe.
