标题： Galaxies at Redshifts z > 5

摘要： 我们描述了我们尝试通过获取中等深度调查（MDS）区域中星系的光度红移，以及非常深的STIS无狭缝光谱学区域中星系的光度红移和光谱红移，来建立非常高红移星系的统计上完整的样本。 基于此分析，我们在一个MDS区域中识别出红移z = 4.92的星系，在一个非常深的STIS区域中识别出红移z = 6.68的星系。 显示英文摘要

摘要： Here we describe our attempts to establish statistically complete samples of very high redshift galaxies by obtaining photometric redshifts of galaxies in Medium Deep Survey (MDS) fields and photometric and spectroscopic redshifts of galaxies in very deep STIS slitless spectroscopy fields. On the basis of this analysis, we have identified galaxies of redshift z = 4.92 in an MDS field and of redshift z = 6.68 in a very deep STIS field.
