Probing the Primordial Universe with the Large-Scale Structure and the CMB: from Systematic Errors to Fundamental Physics

这个项目的目标是研究星系的分布，以检验统计各向同性假设，即宇宙在天空中的每个方向平均看起来都是一样的。违反统计各向同性的宇宙学起源将使标准分析中用于提取宇宙学参数的基本假设失效。胡特勒博士将在天体物理和仪器系统的存在下，以数字和分析的方式探索使用大规模结构数据来探测膨胀物理。这项工作的广泛影响包括对本科生和研究生的培训。此外，胡特勒博士还将为高中生开设为期两周的暑期课程，作为密歇根州数学和科学学者项目的一部分。他还将与底特律大都市区的高中教师合作，参观他们的机构，在课堂上讲课，并帮助他们开发天文学课程。

The goal of this program is to study the distribution of galaxies to test the assumption of statistical isotropy, which is the idea that the universe, on average, looks the same in every direction in the sky. A cosmological origin of the violation of statistical isotropy would invalidate basic assumptions used in the standard analyses to extract cosmological parameters. Dr. Huterer will explore numerically and analytically the use of large-scale structure data to probe inflationary physics in the presence of astrophysical and instrumental systematics.Broader impacts of the work include training of undergraduate and graduate students. In addition, Dr. Huterer will run a two-week summer course for high school students as part of Michigan Math and Science Scholars program. He will also work with teachers in high-schools from the Detroit metro area, visiting their institutions, giving lectures in classes, and helping them develop astronomy curricula.
