Probing the Epoch of Reionization by identifying (lensed) high-redshift galaxies



Jean-Paul KNEIB

Laboratoire d'Astrophysique de Marseille



Résumé : I will review the recent work conducted in the last year regarding the detection and study of the distant high-redshift (z>6) galaxies. Of particular importance is the recent installation of the WFC3 camera onboard of Hubble which InfraRed imaging channel is delivering the deepest images ever obtained in the 1-1.6 micron window. The new HST images are allowing to identify a large number of high redshift galaxy candidates that can then be follow-up in spectroscopy with 8-10m telescopes. I will discuss whether these findings can account from the reionization of the Universe, and what are the current observational limitations that can be improved with current and future facilities.
