The Cosmic Evolution Survey (COSMOS) is directed at understanding the evolution of galaxies and their environments over cosmic time. It occupies a 2 square degree field in the constellation Sextans that is ideal for peering deep into the universe. as it is not obscured by objects in our own galaxy. This team will compile all available spectroscopic data in the COSMOS field into a uniform database that will provide redshifts for over 168,000 galaxies. These data will significantly enhance the COSMOS archive, giving it enormous value as a tool for future studies. Students will be supported at the University of Texas and the Rochester Institute of Technology. The data will be made available through Zoouniverse for a Citizen Science program. This team will produce an online, interactive database containing all the available spectroscopy over the COSMOS field, including data from published surveys as well as previously un-published data available in public archives and data from telescope archives of multi-object spectrographs. It will contain the available reduced data and data products but when necessary, raw archival observations will be reduced. It will have high quality 2D and 1D spectra, measured redshifts, and a catalog of absorption/emission line fluxes, equivalent widths, and kinematic properties linked to existing multiwavelength imaging data and photometric databases. The database will be used to address important outstanding questions in the fields of cosmology and extragalactic astronomy.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.

宇宙进化调查（COSMOS）旨在了解星系及其环境在宇宙时间内的演变。 它占据了六杆星座的2平方英尺田地，非常适合深入宇宙。因为它没有被我们自己的星系中的物体遮盖。 该团队将在Cosmos字段中将所有可用的光谱数据编译为一个统一的数据库，该数据库将为168,000多个星系提供红移。 这些数据将显着增强宇宙档案，从而使其作为未来研究的工具具有巨大的价值。学生将得到德克萨斯大学和罗切斯特理工学院的支持。数据将通过ZooiNiverse提供公民科学计划。 该团队将生产一个在线交互式数据库，其中包含COSMOS领域的所有可用光谱，包括已发表的调查的数据以及以前未发布的数据，可在公共档案馆中获得，以及来自多目标光谱仪的望远镜档案。 它将包含可用的减少数据和数据产品，但是在必要时，将减少原始档案观测值。 它将具有高质量的2D和1D光谱，测量的红移，以及吸收/发射线通量，等效宽度以及与现有多波长成像数据和光度数据库相关的运动特性的目录。 该数据库将用于解决宇宙学领域和外层天文学领域中重要的重要问题。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响评估标准，被认为值得通过评估来提供支持。
