Abstract:
Cosmological reionization - the process of ionization of the bulk of cosmic gas
by ultra-violet radiation from primeval galaxies - is by far the most dramatic
event that occurred in the universe since the formation of the first star. I
will overview recent observational and theoretical progress (and regress) in our
understanding if reionization, and will discuss the future observational and
theoretical avenues that are going to open for us in the near futureNick
