The pan-chromatic Cosmic Evolution Survey (COSMOS) provides the ideal basis to perform a comprehensive study of black hole and stellar mass growth in galaxies, reaching well beyond the peak epoch of active galactic nuclei (AGN) growth and star formation activity, and with particular attention to the influence of environment and the cosmic large scale structure. We have been leading the radio and (sub)mm observational efforts for COSMOS for a decade and we now intend to use of recently awarded large observational programs for COSMOS to address some outstanding issues of galaxy evolution: What is the relative importance of stellar mass, environment, and morphology for stellar mass growth in galaxies as a function of cosmic time? What are the typical host galaxy properties and mass growth rates of AGN, and how do they change over time? What is the role of radio-identified AGN in the regulation of stellar mass growth in galaxies? Our study will be based on new 10 cm observations of the full 2 square degree COSMOS field, facilitated through our large (384 hrs.) JVLA program. These unprecedented deep and wide imaging data will required careful quality assurance and the development of novel imaging and analysis techniques. Funding is requested for the technical and scientific exploitation of this novel data, in close collaboration with the group of Prof. Vernesa Smolcic at the University of Zagreb, for one experienced post-doc to focus on AGN-related topics and the (sub)mm survey data, and for one PhD student for the star formation aspects and JVLA radio data analysis.

泛体宇宙进化调查（COSMOS）为对星系中的黑洞和恒星质量生长进行了全面研究提供了理想的基础，远远超出了活性银河系核（AGN）生长和恒星形成活性的峰值，并特别关注环境和宇宙大规模结构的影响。我们一直在领导广播和（子）MM观察性宇宙的观察工作已有十年了，现在我们打算使用最近授予的大型观察计划来解决Galaxy Evolution的一些杰出问题：恒星质量，环境，环境和形态的相对重要性是在星系中出现稳定的质量增长的稳定性质量，即宇宙时间？ AGN的典型宿主星系特性和质量增长率是什么？它们会随着时间的推移而变化？放射识别的AGN在星系中恒星质量增长中的作用是什么？我们的研究将基于对整个2平方宇宙场的新10厘米观测，这是通过我们的大型JVLA计划促进的。这些前所未有的深层成像数据将需要仔细的质量保证以及新型成像和分析技术的发展。要求资金与萨格勒布大学的Vernesa Smolcic教授密切合作，要求对这一新数据进行技术和科学剥削，以供一位经验丰富的大多数人与AGN相关的主题和（子）MM调查数据，并为一名PhD学生以及一名PhD学生进行Star组和JVLA无线电数据分析。
