This program will use the newly constructed POLARBEAR 3.5-meter-diameter off-axis telescope near ALMA in Chile for observations of cosmic microwave background (CMB) polarization, in order to measure or constrain primordial gravitational B-modes and CMB lensing. The data will be used to map large scale structure and constrain neutrino masses and early dark energy models. The award will fund both operation of the telescope and production of the scientific results. Broader impacts of the work include training of graduate students and a postdoc, collaboration with Chilean and Japanese scientists, and outreach to low-income and under-represented high school students.

该方案将利用智利阿尔马附近新建的3.5米直径离轴望远镜观测宇宙微波背景偏振，以便测量或限制原始引力B模式和宇宙微波背景透镜。这些数据将用于绘制大尺度结构，约束中微子质量和早期暗能量模型。 该奖项将资助望远镜的运作和科学成果的产生。 这项工作的更广泛影响包括培训研究生和博士后，与智利和日本科学家合作，以及向低收入和代表性不足的高中生提供服务。
