摘要:

我们已经开始了一个系统的搜索强透镜的候选人在ESO公众调查KiDS的基础上,在红移范围$0.1<z<0.5$的大质量星系的视觉检查。作为试点项目,我们已经检查了100平方米。度,其与SDSS重叠,并且其中存在已知的透镜用作对照样品。利用VST/OmegaCAM的卓越图像质量、颜色信息和精确的模型减影图像,我们发现了18个新的透镜候选者,需要光谱确认来确认它们的透镜性质并研究透镜星系的质量分布。

英文摘要:

We have started a systematic search of strong lens candidates in the ESO public survey KiDS based on the visual inspection of massive galaxies in the redshift range $0.1<z<0.5$. As a pilot program we have inspected 100 sq. deg., which overlap with SDSS and where there are known lenses to use as a control sample. Taking advantage of the superb image quality of VST/OmegaCAM, the colour information and accurate model subtracted images, we have found 18 new lens candidates, for which spectroscopic confirmation will be needed to confirm their lensing nature and study the mass profile of the lensing galaxies.
