Submillimeter Galaxies

威尔逊博士和他的团队将开展一项研究计划，分析和理解最近用他们的1mm波长测热仪相机（称为AzTEC）拍摄的数据，以测量宇宙领域（天空的一个区域，已在许多波段进行了广泛研究）星系团内或透镜内亚毫米星系（smg）的毫米连续尘埃发射。这是迄今为止对SMG人口进行的最大规模的调查。该团队将通过集群环境中SMG种群的进化来研究分层结构的形成和进化。这项工作将利用许多射电望远镜、毫米望远镜和光学望远镜的全色观测结果。由此产生的数据集将指导数值模拟和半解析结构形成理论。该项目还将在一系列大型集群中绘制小规模Sunyaev-Zeldovich排放图，以便量化合并的重要性。

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.
