Cosmology from Non-Linear Weak Lensing

该计划的目标是开发一套大型的宇宙学射线追踪模拟，以创建一个模拟星系弱透镜图的库，以便通过检查和组合几种不同的非线性统计来研究它们的宇宙学信息内容。将特别注意重子效应和其他系统误差，并建立工具以最好地提取宇宙学信息。仿真库和模拟器将是实现大型天气巡天望远镜和其他未来弱透镜数据集的全部潜力所必需的。这项工作的广泛影响包括对本科生和研究生的培训，模拟数据的发布，以及通过在美国自然历史博物馆的玫瑰地球与空间中心的工作向公众宣传。

The goal of this program is to develop a large suite of cosmological ray-tracing simulations to create a library of simulated maps of weak lensing by galaxies, in order to study their cosmological information content by examining and combining several different non-linear statistics. Special attention will be paid to baryonic effects and to other systematic errors, and tools will be built to best extract the cosmological information. The simulation library and emulator will be necessary to realize the full potential of the Large Synoptic Survey Telescope and other future weak lensing datasets.Broader impacts of the work include training of undergraduate and graduate students, release of simulation data, and outreach to the public via work at the Rose Center for Earth and Space at the American Museum of Natural History.
