The goal of this work is to address several timely questions about the analysis and interpretation of observations of the cosmic microwave background (CMB) radiation, with particular emphasis on observations of CMB polarization. CMB observations provide a snapshot of the Universe at an age of a few hundred thousand years, and the spectrum of CMB temperature variations (anisotropy) contains a wealth of information, e.g., providing strong evidence that the Universe is flat, giving measurements of the amounts of dark matter and dark energy, and supporting the theory of inflation. Broader impacts of the work include training of undergraduate graduate students. This is an RUI (Research at Undergraduate Institutions) proposal in which a number of undergraduate students will be introduced to and trained in developing simulations of CMB polarization telescopes for the future. Dr. Bunn also leads regular observing nights for the public using the campus telescope. A number of the activities will be undertaken, ranging from mathematical analyses, to simulations, to pedagogical expositions,and will include studies of CMB anomalies and E/B mode decomposition.

这项工作的目标是解决几个及时的问题，分析和解释宇宙微波背景辐射（CMB）的观测，特别强调CMB偏振的观测。 宇宙微波背景辐射的观测提供了几十万年前宇宙的快照，宇宙微波背景辐射温度变化（各向异性）的光谱包含了丰富的信息，例如，它提供了强有力的证据证明宇宙是平坦的，给出了暗物质和暗能量的测量结果，并支持了暴胀理论。 这项工作的更广泛影响包括对本科研究生的培训。这是一项RUI（本科院校研究）提案，其中将向一些本科生介绍并培训未来CMB偏振望远镜的模拟开发。 邦恩博士还定期使用校园望远镜为公众举办观测之夜。 将开展一些活动，从数学分析到模拟，再到教学论述，并将包括对CMB异常和E/B模式分解的研究。
