Cosmic Microwave Background Radiation Studies at the South Pole

该项目继续并改进了加州大学圣巴巴拉分校之前在南极成功测量到的宇宙微波背景辐射(CMBR)各向异性。CMBR是宇宙诞生仅几十万年后遗留下来的残余辐射。CMBR中的任何各向异性都揭示了早期宇宙的结构。因为现在到达地球的残余辐射是在被水蒸气吸收的波长范围内，所以有必要在大气极端寒冷(因此非常干燥)的地方进行这些测量，比如南极，或者从大气上方进行测量。加州大学圣巴巴拉分校的小组是粒子天体物理中心的一部分，非常有资格和装备来开展这项研究。该奖项还包括支持本科生参与研究的资金。

This project continues and improves upon the University of California at Santa Barbara's previous successful measurements of the Cosmic Microwave Background Radiation (CMBR) anisotropy from South Pole, Antarctica. The CMBR is relict radiation left over from just a few hundred thousand years after the creation of the universe. Any anisotropies in the CMBR reveal the structure of the early universe. Because relict the radiation now reaching the Earth is in a wavelength range which is absorbed water vapor, it is necessary to make these measurements from places where the atmosphere is extremely cold (and therefore dry), like South Pole, or from above the atmosphere. The University of California Santa Barbara group is part of the Center for Particle Astrophysics and is extremely well qualified and equipped to carry out this research. The award also includes funds for the support of undergraduate students to participate in the research.
