Dr. Wilson and his team will carry out a research program to analyze and understand recent data taken with their 1mm wavelength bolometer camera (called AzTEC) to measure millimeter continuum dust emission from submillimeter galaxies (SMGs) within, or lensed by, galaxy clusters in the COSMOS field (a region of the sky that has been studied extensively at many wavebands). This is the largest survey to date of the SMG population. The team will study hierarchical structure formation and evolution via the evolution of the SMG population in cluster environments. The work will utilize panchromatic observations resulting from a number of radio, millimeter, and optical telescopes. The resulting dataset will guide numerical simulations and semi-analytic structure formation theories. The project will also map the small-scale Sunyaev-Zeldovich emission in a suite of large clusters in order to quantify the importance of mergers.

Wilson 博士和他的团队将开展一项研究计划，分析和理解使用 1 毫米波长测辐射热计相机（称为 AzTEC）拍摄的最新数据，以测量 COSMOS 场（已在多个波段进行广泛研究的天空区域）中星系团内或星系团透镜下的亚毫米星系 (SMG) 的毫米连续尘埃发射。 这是迄今为止对 SMG 人群进行的最大规模的调查。该团队将通过集群环境中SMG种群的进化来研究层次结构的形成和进化。这项工作将利用许多射电望远镜、毫米波望远镜和光学望远镜进行的全色观测。所得数据集将指导数值模拟和半解析结构形成理论。该项目还将绘制一系列大型集群中的小规模 Sunyaev-Zeldovich 排放图，以量化合并的重要性。
