This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This research program will address several timely questions about the analysis and interpretation of observations of the cosmic microwave background (CMB) radiation, with particular emphasis on upcoming observations of CMB polarization and design of CMB polarization telescopes. Techniques will be developed for optimizing the design of future instruments, with particular emphasis on interferometers, which have been less well-studied than single-dish telescopes. Numerical methods for extracting the weak but important B (magnetic field) component from a polarization map will be developed. Finally, a detailed study will be performed of possible explanations for several anomalies in the large-scale maps of CMB temperature anisotropy. Broader impacts of this program include undergraduate student training in research and participation in the Richmond Physics Olympics.

该奖项根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金。该研究计划将解决有关宇宙微波背景（CMB）辐射观测的分析和解释的几个及时问题，特别强调即将进行的 CMB 偏振观测和 CMB 偏振望远镜的设计。将开发优化未来仪器设计的技术，特别是干涉仪，与单口径望远镜相比，干涉仪的研究较少。将开发从极化图中提取微弱但重要的 B（磁场）分量的数值方法。最后，将对大比例尺宇宙微波背景温度各向异性图中的几种异常现象进行详细研究。 该计划的更广泛影响包括本科生研究培训和参加里士满物理奥林匹克运动会。
