The team will search for galaxy clusters and protoclusters in the distant Universe, back to the time when the first clusters were forming, allowing for detailed studies of the most massive galaxies in the universe at the time when they were rapidly growing. The program is based upon catalogs created by NASA’s Wide-field Infrared Survey Explorer (WISE), a space-based observatory that performed an all-sky survey in the infrared. Combining the WISE data with catalogs from the Dark Energy Camera (DECam) on NSF’s Blanco telescope at Cerro Tololo Interamerican Observatory in Chile will allow the team to determine where the first clusters are forming in a 3D volume of the universe. The project also includes a joint virtual public viewing night program at both institutions using remote observing from the Rosemary Hill Observatory. This plan enables public engagement during the pandemic and will expand the reach of public observing programs in both states post-covid. This project will detect and characterize the massive galaxy cluster population at 0.5z2 over 10,480 sq. degrees, building upon a previous cluster survey by the same team, which focused upon galaxy clusters at z~1. The resulting cluster sample will enable detailed investigations of the evolution of massive galaxies in the most overdense environments since the epoch of peak star formation and rapid mass assembly. By extending the redshift baseline to z = 2, the project will reach into the era of protoclusters, in which the first massive clusters are just forming and embedded in larger scale protocluster environments comprised of dense filaments and less massive groups that will be accreted by the central clusters at later times. A combination of DECam and WISE data will be used to compute Bayesian photometric redshift probability distributions for the WISE galaxy sample and then to detect cluster scale overdensities within a 3-dimensional data cube. The PIs will foster the career development of the students working on this project.. The team will initiate and run a joint virtual public night program at their institutions using remote observing from the Rosemary Hill Observatory. This plan enables public engagement during the pandemic and will expand the reach of public observing programs in both states post-covid.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.

该团队将在遥远的宇宙中寻找星系团和原星系团，追溯到第一个星系团形成的时候，以便详细研究宇宙中最大的星系在它们迅速成长的时候。该计划是基于美国宇航局的广域红外巡天探测器（WISE）创建的目录，WISE是一个在红外线上进行全天巡天的天基天文台。将WISE数据与位于智利Cerro Tololo Interamerican天文台的NSF布兰科望远镜上的暗能量相机（DECam）的目录相结合，将使该团队能够确定第一个星系团在宇宙的3D体积中形成的位置。该项目还包括一个联合的虚拟公众观看夜间节目在这两个机构使用远程观测从迷迭香山天文台。该计划使公众能够在大流行期间参与进来，并将在新冠肺炎后扩大这两个州的公众观察计划的覆盖范围。该项目将探测和表征10，480平方英尺的0.5z2大质量星系团人口。度，建立在以前的集群调查由同一个团队，重点是星系团在z~1。由此产生的星系团样本将使详细调查的大质量星系的演变，在最过密的环境，因为时代的高峰星星形成和快速质量组装。通过将红移基线扩展到z = 2，该项目将进入原星系团时代，其中第一个大质量星系团刚刚形成并嵌入由密集细丝和较小质量的群体组成的较大规模的原星系团环境中，这些群体将在稍后的时间被中心星系团吸积。DECam和WISE数据的组合将被用来计算贝叶斯光度红移概率分布的WISE星系样本，然后检测集群规模内的三维数据立方体的过密度。PI将促进参与该项目的学生的职业发展。该团队将在他们的机构发起并运行一个联合虚拟公共夜间项目，使用迷迭香山天文台的远程观测。该计划使公众能够在大流行期间参与进来，并将在新冠肺炎后扩大这两个州的公众观察项目的覆盖范围。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。
