Abstract

High redshift science has been rapidly advancing in recent years on both theoretical and observational fronts However it is still vastly unclear whether galaxies could have reionized the universe on what timescale and what are the properties of these galaxies I will review results from several recent projects we have been involved in aimed to enhance our understanding of the first galaxies and the reionization process In the first part of the talk I will review cluster lensing and recent advancements in lensing related science and in the second part I will concentrate on high redshift galaxies I will show that the crossroad of the two fields has been particularly useful to boost high redshift science and our view of the reionization epoch New efforts now underway with HST Spitzer and 10m ground based telescopes will be overviewed including some exciting results from Keck that potentially challenge our current understanding of reionization Possible scenarios for reconciling this tension will be reviewed
