摘要：
Practical considerations dictate two basic strategies to find very high redshift galaxies: going very deep in small fields (e.g. the HDFs) or doing shallower, wide area surveys which target the bright end of the luminosity function. A third approach which combines some of the advantages of both is to look for strongly magnified objects in the fields of lensing clusters. We present results from such an ongoing program, which has already yielded seven spectroscopically confirmed z > 4 galaxies, and several candidates to z > 6 galaxies. We also discuss the prospects for finding z similar to 6.5 galaxies with HST and the Advanced Camera for Surveys.
