Precision measurements of the cosmic microwave background radiation seek a clearer picture of the physics of the Big Bang. The telescopes that take such data also capture light from stars and galaxies that emit at the same wavelengths. This project would build software pipelines that take advantage of these measurements. Each day, these telescopes scan the sky and make an updated image, letting sources that are variable to be identified. During this decade, upgraded telescopes will produce more and better data of this kind. Such time-resolved data will permit new classes of unknown phenomena to be found. This may include exceptional supernovae, gamma ray bursts, tidal disruptions of stars around supermassive black holes, stellar flares and the discovery of additional bodies in the solar system, including a hypothetical and undiscovered Planet 9. The excitement of this project will be conveyed to the public via a variety of outreach programs including one targeting people living in rural areas near Tallahassee.New, time-domain studies of wide-field millimeter-wave surveys are opening a vast, unexplored discovery space. In this project, millimeter-wave transients and point-like sources will be identified using data from the Advanced Atacama Cosmology Telescope, now surveying areas that exceed 18,000 square degrees, and the Simons Observatory, which by the mid-2020s will produce more sensitive measurements over a similar area. Software tools and pipelines will be developed to (1) develop and implement a system to mine daily Simons Observatory data based on real-time transient alerts; (2) perform triggered and blind searches for mm-wave transients in archival and live data; (3) prepare and release point source catalogs in temperature and polarization for the ACT and Simons Observatory surveys; and (4) support a follow-up program for high redshift source candidates. The project supports a number of outreach programs that involve the general public, K-12 students and undergraduate as well as graduate students.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.

宇宙微波背景辐射的精确测量值更清晰地了解大爆炸的物理。 采用此类数据的望远镜还捕获了从相同波长发射的星系和星系的光。 该项目将建立利用这些测量值的软件管道。每天，这些望远镜扫描天空并制作一个更新的图像，允许可以识别的可变来源。 在这十年中，升级的望远镜将产生更多这样的数据。 这种时间分辨的数据将允许找到新的未知现象类。这可能包括特殊的超新星，γ射线爆发，超级质量黑洞周围的恒星潮汐破坏，恒星的耀斑以及在太阳系中发现其他尸体，包括假设的和未发现的星球9。该项目的兴奋将通过该项目的范围内的范围内的范围内的范围内的范围的人传达给公众，包括一定的范围内的范围内的范围，包括范围内的范围内的范围。毫米波调查正在开放一个巨大的，未开发的发现空间。 在这个项目中，将使用来自高级Atacama宇宙学望远镜的数据来识别毫米波瞬变和类似点样的来源，该数据现在调查了超过18,000平方英尺的测量区域，而Simons天文台则将在2020年代中期产生更敏感的测量。 将开发软件工具和管道以（1）开发和实施一个系统，以根据实时瞬态警报来开采每日Simons天文台数据； （2）在档案和实时数据中对MM波瞬变进行触发和盲目搜索； （3）该法案中的温度和极化准备和释放点源目录和Simons天文台调查； （4）支持高红移源候选者的后续计划。该项目支持许多涉及公众，K-12学生和本科生以及研究生的外展计划。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和更广泛影响的评估评估标准来通过评估来支持的。
