Collaborative Research: Toward a Uniform and Complete Spectroscopic Archive for the COSMOS Legacy Field

宇宙演化调查(COSMOS)旨在了解星系及其环境在宇宙时间内的演化。它在六人星座占据了2平方度的视野，这是深入观察宇宙的理想之选。因为它不会被我们银河系中的物体遮挡。该团队将把宇宙场中所有可用的光谱数据汇编到一个统一的数据库中，该数据库将提供超过16.8万个星系的红移。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。学生将在德克萨斯大学和罗切斯特理工学院得到支持。这些数据将通过Zoouniverse为公民科学项目提供。该小组将建立一个在线互动数据库，其中包含宇宙领域所有可用的光谱数据，包括已公布的调查数据以及公共档案馆以前未公布的数据，以及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，原始档案观察数据将减少。它将拥有高质量的2D和1D光谱、测量的红移以及与现有多波长成像数据和光度数据库相关联的吸收/发射线通量、等效宽度和运动学属性的目录。该数据库将用于解决宇宙学和河外天文学领域的重要悬而未决的问题。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

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.
