AST-0098048Bunn, E.F.This research will improve methods of analysis for large data sets in Cosmic Microwave Background (CMB) studies, including refinements of algorithms for analyzing large maps and removing foreground contamination. The methods will be tested using simulations, and then applied to datasets generated by BEAST, an existing balloon-borne telescope for measuring CMB anisotropies, and eventually all-sky satellite observations. Extraction of statistics beyond the simple power spectrum, such as non-gaussianity and isotropy of the fluctuations, is the main goal of the research.***

AST-0098048 Bunn，E.F.这项研究将改进宇宙微波背景（CMB）研究中大型数据集的分析方法，包括改进分析大型地图和消除前景污染的算法。 这些方法将使用模拟进行测试，然后应用于BEAST生成的数据集，BEAST是一种现有的用于测量CMB各向异性的球载望远镜，最终应用于全天卫星观测。 提取简单功率谱之外的统计量，如波动的非高斯性和各向同性，是研究的主要目标。
