Discovering Properties of Neutrinos, Inflation, and Dark Energy Using the Cosmic Microwave Background

这项研究的目的是对美国国家科学基金会赞助的ACTPol和AdvACTPoll实验进行数据分析。这些实验试图更好地理解大爆炸宇宙学中复合时遗留下来的热辐射(被称为宇宙微波背景，或CMB)。ACT是阿塔卡马宇宙学望远镜，直径6米，位于智利北部海拔17,000英尺的毫米波长望远镜。这项工作的更广泛影响包括对女本科生的指导，以及对研究生和博士后的研究培训。获奖者还将参观小学和博物馆，领导天文教育活动，这是应科院计划的一部分。研究重点将集中在中巴的科学，包括充气和透镜B模，以及中巴的弱透镜。前者告诉我们大爆炸期间宇宙膨胀的知识，后者可以提供关于中微子质量的信息。还将创建带有偏振的毫米天空模拟。

The objective of this research is to undertake data analysis for the NSF-sponsored ACTpol and AdvACTpol experiments. These experiments are seeking to better understand the thermal radiation (known as the cosmic microwave background, or CMB) left over from the time of recombination in Big Bang cosmology. The ACT is the Atacama Cosmology Telescope, a 6m-diameter millimeter wavelength telescope located at 17,000 ft elevation in northern Chile. Broader impacts of the work include mentoring of female undergraduates, and research training of graduate students and a postdoc. The awardee will also visit elementary schools and museums to lead astronomy education activities as part of the Project ASTRO program.The research will focus on CMB science including inflation and lensing B modes, and CMB weak lensing. The former informs our knowledge of cosmic inflation during the big bang, and the latter can provide information on the mass of neutrinos. Millimeter sky simulations with polarization will also be created.
