Collaborative Proposal: An Investigation of the Formation and Evolution of Globular Cluster Systems and their Host Galaxies

AST 0406876 PI：基思阿什曼研究所：密苏里州大学-堪萨斯在这项合作工作中，基思阿什曼和斯蒂芬泽普夫博士将研究球状星团系统及其宿主星系的形成和演化，通过地面观测研究和半分析理论模型。 该计划将侧重于两个研究领域。 其中第一个是提高通过宽视场成像的球状星团的总数，颜色和空间分布的测定，并开发理论工具，以限制从这些数据的金属贫球状星团形成的网站。 第二个领域是通过使用光学到近红外颜色、光学光谱学和发展星系和星团形成的半分析模型，对球状星团人口的年龄和金属丰度进行综合观测和理论研究。 该计划将促进教学，培训和学习，包括各级学生进入研究计划，通过将研究纳入入门课程，并通过参与面向公众的推广计划。

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.
