The light of the Cosmic Microwave Background (CMB) carries a wealth of untapped information including how the Universe was created and the properties of the elusive neutrino particles. A new generation of CMB experiments are coming online, due in part to a significant investment in experimental infrastructure. However, there is a critical need to complement this with a significant investment in the analysis of the current and upcoming data. This award will allow the necessary data analysis to measure the masses of the neutrino particles with Advanced ACTPol (AdvACT) data. This award will also allow the development of analysis to detect gravitational waves from the early Universe, using Simons Observatory (SO) data,to understand how the Universe was created. The broader impacts of this proposal are that the PI will bring the excitement of cosmological research to young female undergraduates, elementary-school students, and the public. The PI will do this by: 1) mentoring and instructing women undergraduates through the Stony Brook Women in Science and Engineering (WISE) Honors program, by 2) being a ``visiting classroom astronomer'' in local elementary schools as part of the Project ASTRO program, and by 3) giving public talks several times per year on a variety of topics such as Dark Matter, Dark Energy, the Early Universe, Gravitational Waves, and the Cosmic Neutrino Background. The first research objective of this proposal is to measure how much gravitational lensing has bent the CMB light as this light has travelled to us, using AdvACT data, in order to measure the masses of the neutrino particles. The second research objective is to co-develop the B-mode delensing analysis to detect primordial gravitational waves, as well as oversee all CMB lensing analyses for SO needed for key SO science goals. The proposed research is potentially transformational because it could result in a detection of the sum of the neutrino masses with AdvACT data. In addition, this research could enable a detection of primordial gravitational waves with SO data, shedding critical light on how our Universe began.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

宇宙微波背景（CMB）的光带有大量未开发的信息，包括如何创建宇宙以及难以捉摸的中微子颗粒的特性。 新一代的CMB实验即将在线进行，部分原因是对实验基础设施进行了大量投资。 但是，在对当前和即将到来的数据的分析中进行大量投资，迫切需要对此进行补充。 该奖项将允许使用高级ACTPOL（ADVACT）数据的中微子粒子的质量进行必要的数据分析。 该奖项还将允许使用Simons天文台（SO）数据来检测早期宇宙中的引力波，以了解如何创建宇宙。该提议的更广泛的影响是，PI将使宇宙学研究的兴奋带给年轻的女性本科生，小学学生和公众。 PI将通过：1）通过斯托尼·布鲁克（Stony Brook）在科学和工程学（明智）荣誉计划中指导和指导女性在本地小学的``访问教室天文学家'''作为``访问教室的天文学家''''作为Astro计划的一部分，以及3年的公众谈话，例如早期的狂热狂热，这些狂热的狂热和狂热的狂热，这些狂热的狂热和狂热的早期狂热，这些狂热的狂热和狂热的早期狂热的狂热，``访问教室天文学 背景。 该提案的第一个研究目标是测量在使用ADVACT数据向我们传播的，以测量中微子颗粒的质量时，该光线已弯曲了CMB光的多少重力透镜。第二个研究目标是共同开发B模式删除分析，以检测原始引力波，并监督所有CMB镜头分析的关键SO SO SO GOAMES所需的SO。拟议的研究具有潜在的转化，因为它可能导致使用ADVACT数据的中微子质量之和的检测。此外，这项研究可以通过SO数据来检测原始引力波，从而阐明了我们的宇宙的开始。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子的评估来支持的，并具有更广泛的影响。
