This goal of this proposal is to develop advanced techniques designed to place precise constraints on cosmological parameter estimates through weak gravitational lensing analysis of ongoing and future galaxy surveys, in particular the Dark Energy Survey. This will be achieved by improving weak gravitational lensing shape measurement algorithms and data calibration techniques.Broader impacts of the work include training of a graduate student, and sharing of lensing computer codes through the GalSim project. The work will contribute to the future success of the Large Synoptic Survey Telescope (LSST).

该提案的目标是开发先进的技术，旨在通过对正在进行的和未来的星系调查，特别是暗能量调查的弱引力透镜分析，对宇宙学参数估计进行精确的限制。这将通过改进弱引力透镜形状测量算法和数据校准技术来实现。这项工作的更广泛影响包括培训一名研究生，以及通过GalSim项目共享透镜计算机代码。 这项工作将有助于大型综合巡天望远镜（LSST）未来的成功。
