我们介绍了我们对透镜星系团的深入调查所获得的结果，目的是限制z6-11处恒星形成星系的丰度。透镜放大改进了新一代近红外多目标光谱仪(如EMIR/GTC)的搜索频率和后续的光谱研究。从候选者的光度样本导出的UV光度函数没有显示Bouwens等人在z6-7时观察到的周转。(2005)走向光明的尽头。由于这个原因，SFR密度与直到z 10的恒定值一致。这种关于空白区域的系统趋势可能是由于年龄对年龄的变化、来自z中期的正的磁化偏置，和/或由伪源造成的残留污染。
We present the results obtained from our deep survey of lensing clusters aimed at constraining the abundance of star-forming galaxies at z 6-11. Lensing magnication improves the search eciency and subsequent spectroscopic studies with the new generation of NIR multi-object spectrographs (e.g. EMIR/GTC). The UV Luminosity Function derived from the photometric sample of candidates does not show the turnover observed at z 6-7 by Bouwens et al. (2005) towards the bright end. For this reason, the SFR density is consistent with a constant value up to z 10. This systematic trend with respect to blank elds could be due to eld-to-eld variance, positive magnication bias from mid-z EROs, and/or residual contamination by spurious sources.
