SUMMARY:The evolution of galaxies during the first billion years.
DESCRIPTION:The evolution of galaxies during the first billion years.\nDr. 
 Nicolas Laporte\n\nEvolution of galaxies is relatively well known up to z 
 ~ 5, but beyond  this limit and regarding the few number of galaxies confi
 rmed by  spectroscopy, their evolution is still uncertain. In the last fiv
 e  years, many projects and instruments aiming at pushing the limits of th
 e  Universe have emerged. Among them, the WIRCam Ultra Deep Survey (WUDS),
   a very large (~400 arcmin^2 field of view) and deep (m_H=27.00 AB)  surv
 ey covering wavelength from Y to Ks bands, dedicated to select the  bright
 est sources at z > 4.5, has just been finished.This survey  takes benef
 it from the deep images from the CFHT-LS (Groth Strip) in u,  g, r, i and 
 z-band to improve the wavelength coverage and thus the  determination of p
 hotometric redshift in each sample. The evolution of  galaxies has been st
 udied through the evolution of the UV Luminosity  Function from z~5 up to 
 z~9. During this talk I will present you the  WIRCam Ultra Deep Survey and
  the most popular method used to select the  very high-redshift sources. T
 hen I will focus on the determination of  the luminosity function and on t
 he implications of this evolution on the  Epoch of Reionization. I will fi
 nish this presentation by giving some  perspectives, and especially the re
 sults that we can expected from  futures instruments and telescopes (e.g. 
 EMIR @ GTC, KMOS and MUSE @  VLT, JWST, E-ELT).
