项目摘要
This project funds the ongoing operation of the Parallel Imager for Southern Cosmology Observations (PISCO), a fast, general-purpose imaging photometer in Chile. The South Pole Telescope (SPT) consortium is conducting the SPT-3G deep millimeter-wave continuum survey, which is detecting thousands of previously unknown galaxy clusters and groups. PISCO observations play a key role in the production of an extensive catalog of galaxy clusters over about 9% of the sky. The resulting searchable public database will include imaging as well as spectroscopy in the optical, infrared, and X-ray, contributing to a wide variety of scientific studies. This project also funds the operation and maintenance of a MicroObservatory telescope for remote STEM education and outreach, operated as part of the Smithsonian Astrophysical Observatory’s Science Education Department Robotic Telescope Network for the online STEM learning community.This program will produce photometric and spectroscopic catalogs of volume-complete samples of galaxy clusters over a 4000 square degree area of sky. After analyzing candidate cluster positions in existing survey data such as DES and VISTA, the SPT team will: (1) make the additional photometric imaging observations needed for completeness in redshift and mass limit, (2) obtain weak lensing measurements during periods of excellent seeing for a representative sub-sample of these clusters, (3) make these evolving data sets available to the astronomical and STEM learning communities in both raw and reduced form, through publications and a web-accessible, searchable archive, and (4) analyze the data for cosmology and the determination of neutrino properties.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.
该项目为正在运行的南方宇宙学观测平行成像仪(PISCO)提供资金,这是智利的一种快速通用成像光度计。南极望远镜(SPT)联盟正在进行SPT- 3g深毫米波连续体调查,该调查正在探测数千个以前未知的星系团和星系群。皮斯科的观测在生成覆盖约9%天空的星系团的广泛目录中发挥了关键作用。由此产生的可搜索的公共数据库将包括成像以及光学、红外和x射线的光谱学,为各种科学研究做出贡献。该项目还资助了用于远程STEM教育和推广的微型天文台望远镜的运营和维护,该望远镜是史密森天体物理天文台科学教育部机器人望远镜网络的一部分,用于在线STEM学习社区。这个项目将生成4000平方度天空中星系团体积完整样本的光度和光谱目录。在分析了现有调查数据(如DES和VISTA)中的候选聚类位置后,SPT团队将:(1)进行额外的光度成像观测,以确保红移和质量极限的完整性;(2)在这些星团的代表性子样本的良好视力期间获得弱透镜测量;(3)通过出版物和网络可访问的可搜索档案,以原始和简化的形式向天文学和STEM学习社区提供这些不断发展的数据集;(4)对宇宙学数据和中微子性质测定数据进行分析。该奖项反映了美国国家科学基金会的法定使命,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。
