RUI: Cosmic microwave background polarization analysis with undergraduates

这项工作的目的是解决有关宇宙微波背景（CMB）辐射观测分析和解释的几个及时问题，特别强调对CMB极化的观测。CMB观测提供了几十万年前宇宙的快照，CMB温度变化的光谱（各向异性）包含了丰富的信息，例如，提供了宇宙是平坦的有力证据，给出了暗物质和暗能量的测量值，并支持了暴胀理论。这项工作更广泛的影响包括培养本科生和研究生。这是一项本科院校研究（RUI）提案，其中将向一些本科生介绍并培训他们为未来开发CMB偏振望远镜的模拟。邦恩博士还定期带领公众使用校园望远镜进行夜间观测。将进行一些活动，从数学分析、模拟到教学展示，并将包括研究宇宙微波背景异常和E/B模式分解。

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.
