摘要:

我们描述并提出了斯隆数字巡天(SDSS)中的一个弱透镜巡天($\rm{z}\lesssim0.1$)星系团的初步结果。在第一次研究中,星系团是从\citet{miller05}和\citet{berlind06}的SDSS光谱星系团目录中选择的。我们报告了七个单独的低红移星系团弱透镜测量结果,包括:A2048,A1767,A2244,A1066,A2199,和两个星系团特别确定的C4算法。我们对SDSS中邻近星系团的弱透镜观测计划最终将覆盖$\sim 200$星系团,这是迄今为止对单个星系团进行的最大规模的弱透镜观测。

英文摘要:

We describe and present initial results of a weak lensing survey of nearby ($\rm{z}\lesssim0.1$) galaxy clusters in the Sloan Digital Sky Survey (SDSS). In this first study, galaxy clusters are selected from the SDSS spectroscopic galaxy cluster catalogs of \citet{miller05} and \citet{berlind06}. We report a total of seven individual low redshift cluster weak lensing measurements which include: A2048, A1767, A2244, A1066, A2199, and two clusters specifically identified with the C4 algorithm. Our program of weak lensing of nearby galaxy clusters in the SDSS will eventually reach $\sim 200$ clusters, making it the largest weak lensing survey of individual galaxy clusters to date.
