项目摘要
This program will investigate a new technique to explore the ?Hidden Universe? of Dark Matter and Dark Energy. This will be accomplished via determination of the amplitude of matter fluctuations in the universe through measurements of the thermal Sunyaev-Zeldovich effect (the scattering of Cosmic Microwave Background photons off hot gas in galaxy clusters) and gravitational lensing. The proposed technique will be applied to real data from the Atacama Cosmology Experiment, the Planck experiment and the Subaru telescope.Broader impacts of the work include training of undergraduate and graduate students. In addition, Dr. Spergel has participated in several TV programs on cosmology per year and will continue to do so. He will also continue his program of speaking to elementary school students on measurement and cosmology.
该计划将研究一种新的技术来探索?隐藏宇宙?暗物质和暗能量 这将通过测量热Sunyaev-Zeldovich效应(星系团中热气体对宇宙微波背景光子的散射)和引力透镜来确定宇宙中物质波动的幅度来实现。所提议的技术将应用于来自阿塔卡马宇宙学实验、普朗克实验和斯巴鲁望远镜的真实的数据,这项工作的更广泛影响包括培训本科生和研究生。此外,Spergel博士每年参加几个关于宇宙学的电视节目,并将继续这样做。他还将继续他的计划,向小学生讲述测量和宇宙学。
