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.

宇宙演化巡天（Cosmic Evolution Survey，COSMOS）旨在了解星系及其环境在宇宙时间内的演化。 它在六分仪星座中占据了2平方度的区域，这是深入观察宇宙的理想场所。因为它没有被我们银河系中的物体所遮挡。 该团队将把COSMOS领域所有可用的光谱数据汇编成一个统一的数据库，该数据库将提供超过168，000个星系的红移。 这些数据将大大增强COSMOS档案，使其作为未来研究的工具具有巨大价值。学生将得到德克萨斯大学和罗切斯特理工学院的支持。这些数据将通过Zoouniverse提供给公民科学计划。 该团队将创建一个在线交互式数据库，其中包含COSMOS领域所有可用的光谱学，包括来自已公布的调查的数据以及公共档案中以前未公布的数据和来自多目标光谱仪望远镜档案的数据。 它将包含现有的简化数据和数据产品，但在必要时，将减少原始档案观察结果。 它将具有高质量的2D和1D光谱，测量的红移，以及与现有的多波长成像数据和光度数据库相关联的吸收/发射线通量，等效宽度和运动学特性的目录。 该数据库将用于解决宇宙学和河外天文学领域的重要未决问题，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。
