On the Reionization of the Universe

Abstract

I present first principle model calculations for the reionization of the Universe, which provide simple diagnostics to identify the reionization sources. Within this frame, I also discuss the results derived from the Hubble Ultra-Deep Field observations, and the possible need for future observations with JWST to provide the final answer.
