This award is to support measurements of the 14-billion-year cosmic microwave background (CMB) light with the South Pole Telescope (SPT) to address some of the most basic and compelling questions in cosmology: What is the origin of the Universe? What is the Universe made of? What is the mass scale of the neutrinos? When did the first stars and galaxies form and how was the Universe reionized? What is the Dark Energy that is accelerating the expansion of the Universe? The SPT plays a unique role in the pursuit of these questions. Its siting is ideal for ultra-low-noise imaging surveys of the sky at the millimeter and sub-millimeter radio wavelengths. The SPT is supported by the NSF's Amundsen-Scott South Pole Station, which is the best operational site on Earth for mm-wave sky surveys. This unique geographical location allows SPT to obtain extremely sensitive 24/7 observations of targeted low Galactic foreground regions of the sky.The telescope's third-generation, SPT-3G receiver has 16,000 detectors configured for polarization-sensitive observations in three millimeter-wave bands. The proposed operation includes five years of sky surveys to obtain ultra-deep measurements of a 1500 square degree field and to produce and publicly archive essential data products from the survey. The telescope's CMB temperatures and polarization power spectrum will play a central role in probing the nature of current tensions among cosmological parameter estimations from different data sets and determining if their explanation requires physics beyond the current LCDM model. The data will help constraining the Dark Energy properties that affect the growth of large structures through both the CMB lensing and abundance of galaxy clusters. The proposed operations also support SPT's critical role in the Event Horizon Telescope (EHT), a global array of telescopes to image the event horizon around the black hole at the center of Milky Way Galaxy. This award addresses and advances the science objectives and goals of the NSF's "Windows on the Universe: The Era of Multi-Messenger Astrophysics" program.The proposed research activity will also contribute to the training of the next generation of scientists by integrating graduate and undergraduate education with the technology development, astronomical observations, and scientific analyses of SPT data. Research and education are integrated by bringing research activities into the undergraduate classroom and sharing of forefront research with non-scientists extending it beyond the university through a well-established educational network that reaches a wide audience at all levels of the educational continuum. Through museum partnerships and new media, the SPT outreach and educational efforts reach large numbers of individuals while personalizing the experience.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.

该奖项旨在支持利用南极望远镜 (SPT) 对 140 亿年的宇宙微波背景 (CMB) 光进行测量，以解决宇宙学中一些最基本、最引人注目的问题：宇宙的起源是什么？宇宙是由什么构成的？ 中微子的质量尺度是多少？第一批恒星和星系何时形成？宇宙是如何重新电离的？ 加速宇宙膨胀的暗能量是什么？ SPT 在解决这些问题的过程中发挥着独特的作用。它的选址非常适合在毫米和亚毫米无线电波长下对天空进行超低噪声成像调查。 SPT 得到了 NSF 的阿蒙森-斯科特南极站的支持，该站是地球上进行毫米波巡天的最佳操作站点。这种独特的地理位置使 SPT 能够对天空中的目标低银河系前景区域获得极为灵敏的 24/7 观测。该望远镜的第三代 SPT-3G 接收器拥有 16,000 个探测器，配置用于三个毫米波频段的偏振敏感观测。拟议的行动包括为期五年的天空调查，以获得 1500 平方度领域的超深测量，并从调查中生成和公开存档基本数据产品。 该望远镜的 CMB 温度和偏振功率谱将在探索不同数据集的宇宙学参数估计之间当前紧张关系的性质以及确定它们的解释是否需要超出当前 LCDM 模型的物理学方面发挥核心作用。这些数据将有助于限制暗能量特性，这些特性通过宇宙微波背景透镜和丰富的星系团影响大型结构的生长。拟议的操作还支持 SPT 在事件视界望远镜 (EHT) 中发挥关键作用，事件视界望远镜是一个全球性的望远镜阵列，用于对银河系中心黑洞周围的事件视界进行成像。该奖项解决并推进了美国国家科学基金会“宇宙之窗：多信使天体物理学时代”计划的科学目标和目标。拟议的研究活动还将通过整合研究生和本科生来促进下一代科学家的培训技术发展、天文观测和 SPT 数据科学分析的教育。通过将研究活动带入本科生课堂，并与非科学家分享前沿研究，通过完善的教育网络将研究和教育扩展到大学之外，该网络覆盖教育连续体各个层次的广泛受众，从而将研究和教育融为一体。通过博物馆合作伙伴和新媒体，SPT 的外展和教育工作惠及了大量个人，同时提供个性化的体验。该奖项反映了 NSF 的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
