DESCRIPTION:The epoch of re-ionization is a fascinating time in the histor
 y of the Universe and many uncertainties still plague our understanding of
  when and how it occurred.\n\nLyman alphas emitting galaxies at high redsh
 ift offer a powerful probe to study both reionization and the process of g
 alaxy formation.  In particular Lyman alphas emission is an efficient tool
  for identifying young galaxies and for measuring how much neutral hydroge
 n is present in their environment\, thus providing a reionization test tha
 t is independent of the Gunn-Peterson trough observations in quasar spectr
 a.\n\nThe last two years have seen a number of discoveries that offered th
 e first glimpse of the Universe at z=7\, using both space and ground-based
  telescopes.  I will review the most recent observational results on high 
 redshift galaxies and the current constraints that we can place on the rei
 onization epoch using the first statistical samples of spectroscopy confir
 med z=7 Lyman break galaxies\, the evolution of the luminosity functions a
 nd of the clustering strength of Lyalpha emitters.\n
