COSMOS: A Radio and (Sub)mm Study of Starbursts and AGN throughout Cosmic History

COSMOS项目是一项全色(X射线到射电)调查，旨在对z=0.5至3的关键红移范围内的星系和超大质量黑洞演化进行最全面的研究，并特别关注环境和大尺度结构的影响。申请者正在使用VLA、IRAM仪器和APEX领导宇宙项目中的无线电和(亚)毫米观测工作。在未来一段重要的时间里，COSMOS项目将为约束星系形成和大尺度结构的模型提供关键数据。面积覆盖范围足够大，足以克服宇宙差异，并在最大的相关尺度上描绘结构(~100MPC)。我们的射电和(亚)毫米观测是对该项目的基本贡献，包括：(1)识别/表征质量大的、被尘埃遮挡的星爆星系，以量化它们在宇宙恒星形成历史中的作用；(2)追踪恒星形成星系的FIR/射电关联的演变；以及(3)低光度射电活动星系群向高红移的演化。我们请求资助一名博士后和一名博士后从事与无线电相关的科学研究，并资助一名博士后和一名博士后从事正在进行的apex-submm调查，以及对在当前资助期间发现的mm源进行后续观察。

The COSMOS project is a pan-chromatic (X-ray to radio) survey to perform the most comprehensive study of galaxy and super-massive black hole evolution in the crucial redshift range z = 0.5 to 3, with particular attention to the influence of environment and large scale structure. The applicants are leading the radio and (sub)mm observational efforts in the COSMOS project using the VLA, both IRAM instruments, and APEX. For a significant time to come, the COSMOS project will provide key data for constraining models of galaxy formation and large scale structure. The areal coverage is large enough to overcome cosmic variance, and to delineate structure on the largest relevant scales (~ 100 Mpc comoving). Our radio and (sub)mm observations represent a fundamental contribution to the project, including: (i) the identification/characterization of massive, dust-obscured starburst galaxies to quantify their role in the cosmic star formation history, (ii) tracing the evolution of the FIR/radio correlation for star forming galaxies, and (iii) the evolution of low luminosity radio AGN out to high redshift. We request funding for a postdoc and a doctoral student to work on the radio-related science, and for a postdoc and a doctoral student to work on the ongoing APEX-submm survey and on follow-up observations of the mm sources discovered during the current funding period.
