AST 0406876PI: Keith AshmanInst: University of Missouri - Kansas CityIn this collaborative work, Drs. Keith Ashman and Stephen Zepf will study the formation and evolution of globular cluster systems and their host galaxies through ground based observational studies and semi-analytical theoretical models. The program will focus on two areas of research. The first of these is to improve the determination of the total number, color, and spatial distribution of globular clusters through wide-field imaging and to develop theoretical tools to constrain the sites of metal-poor globular cluster formation from these data. The second area is a combined observational and theoretical study of the ages and metallicities of globular cluster populations through the use of optical to near-IR colors, optical spectroscopy and the development of semi-analytical models of galaxy and cluster formation. The program will promote teaching, training, and learning by including students at all levels into the research program, by incorporating research into introductory courses and through involvement in outreach programs for the public.

AST 0406876PI：基思·阿什曼斯特（Keith Ashmaninst）：密苏里大学 - 堪萨斯城（Kansas Cityin）这项合作工作，博士。基思·阿什曼（Keith Ashman）和斯蒂芬·泽普（Stephen Zepf）将通过基于地面的观察性研究和半分析理论模型来研究球状簇系统及其宿主星系的形成和演化。 该计划将重点关注两个研究领域。 首先是通过宽场成像来改善球状簇的总数，颜色和空间分布，并开发理论工具，以从这些数据中限制金属贫困球体集群形成的位点。 第二个领域是通过使用光学到近红色颜色，光谱以及星系和簇形成的半分析模型的发展，对球状簇种群的年龄和金属性进行了合并的观察和理论研究。 该计划将通过将研究纳入入门课程和参与公众的宣传课程中，通过将各级学生纳入研究计划，来促进教学，培训和学习。
