AST-0407343DresslerThis is a very large-scale study of the evolution of galaxies in the environs of clusters, in order to understand the mechanisms by which galaxy evolution is affected by environment. This program is extremely aggressive, in depth and breadth, and will provide enough data of sufficiently high quality to answer important questions about galaxy evolution. As a complement, sophisticated numerical models will identify the particular environments hosting galaxies that will eventually end in various parts of the formed cluster. Observing galaxies in the succession of loci at different redshifts effectively simulates the impossible task of following the evolution of an individual galaxy through cosmic time.The research will be communicated to a broad audience through public lectures, magazine articles, and radio and television programs. The Carnegie Observatories are also embarked on an ambitious program of educational outreach, particularly focused on the disadvantaged minority population of its immediate community. This includes a public lecture series, targeted to the entire community but with associated events for local school children, work with the neighborhood elementary school, and a summer school for minority high school students.

这是对星系团周围星系演化的一项非常大规模的研究，目的是了解星系演化受环境影响的机制。这个项目在深度和广度上都非常积极，将提供足够高质量的数据来回答有关星系演化的重要问题。作为补充，复杂的数值模型将识别出承载星系的特定环境，这些星系最终将在形成的星团的各个部分结束。在不同红移的连续位置上观察星系，有效地模拟了跟踪单个星系在宇宙时间中的演化这一不可能完成的任务。这项研究将通过公开演讲、杂志文章、广播和电视节目传播给广大听众。卡内基天文台还开始了一项雄心勃勃的教育推广计划，特别关注其附近社区的弱势少数民族人口。这包括针对整个社区的一系列公开讲座，以及为当地学生举办的相关活动，与社区小学合作，以及为少数民族高中学生举办的暑期学校。
