Investigations of 2- and 3- point Intrinsic Alignments of Galaxies (II, GI, III, GGI, GII) and their Isolation in Current and Future Lensing Surveys

这项研究的目的是解决弱透镜研究中的内在排列系统学，这是沿着星系调查，以评估宇宙（包括暗物质）的大规模质量分布。这些结果将对未来大型天气巡天望远镜（LSST）的研究具有重要意义。这项工作的更广泛影响包括培训一名研究生，参与让妇女参与物理学的研究项目和高中暑期学生，以及为高中教师举办讲习班讲座和关于宇宙学的一般公众讲座。 这项工作将解决弱透镜研究中各种内在对准所产生的系统误差。其目的是开发和分析2-pt和3-pt的内在对齐措施，从理论，模拟，并从CFHTLenS和VIPERS星系调查的实际测量。

The objective of this research is to address intrinsic alignment systematics in weak lensing studies, which are used along with galaxy surveys to assess the large-scale mass distribution of the universe (including dark matter). The results will be important in the future for studies by the Large Synoptic Survey Telescope (LSST). Broader impacts of the work include training of a graduate student, engaging in research projects that incorporate women in physics and summer students from high schools, and workshop talks for high school teachers and general public talks on cosmology. The work will addresses systematic errors that arise from a variety of intrinsic alignments in weak lensing studies. The aim is to develop and analyze 2-pt and 3-pt intrinsic alignment measures from theory, simulations, and from actual measurements from the CFHTLenS and VIPERS galaxy surveys.
