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.

该计划将研究一种探索“隐藏宇宙”的新技术。暗物质和暗能量。 这将通过测量热苏尼亚耶夫-泽尔多维奇效应（星系团中热气体的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。所提出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数据。这项工作的更广泛影响包括对本科生和研究生的培训。此外，斯佩格尔博士每年都会参加多个有关宇宙学的电视节目，并将继续这样做。他还将继续向小学生进行有关测量和宇宙学的演讲。
