Recent Advances in Cosmological Hydrogen Reionization
  I discuss recent advances in the study of hydrogen reionization, focusing on
progress that was achieved during the years 2010-2011. First, I discuss recent
measurements of the progress of reionization. Next, I discuss recent
observational constraints on the nature and abundance of the dominant ionizing
sources. Finally, I discuss recent progress in modeling reionization. This
review is written for an audience of astronomers who do not specialize in the
high-redshift Universe.
