H-alpha Derived Star-Formation Rates of z~0.5 and z~0.8 Galaxy Clusters

AST-0301328 Finn，RoseDr.芬恩被授予NSF天文学和天体物理学博士后奖学金，在阿默斯特的马萨诸塞州大学开展研究和教育计划。 该项目的主要研究目标是测量星系团中恒星形成的数量和径向依赖性作为红移的函数，以研究影响星系团环境中星星形成和星系演化的主要物理过程。她正在开发一种技术，利用窄带近红外成像，从电离氢的H-α发射中推导出这些遥远星系的恒星形成率。该项目的目标是红移在0.5到0.8之间的星系团。除了她的研究，芬恩博士将设计和教授一个基于项目的观察技术本科课程，包括三个模块的距离指标。其中一个关于造父变星的单元将经过改编，供高中学生使用，并将通过现有的教师培训方案传授给教师。***

AST-0301328Finn, RoseDr. Finn is awarded an NSF Astronomy and Astrophysics Postdoctoral Fellowship to carry out a program of research and education at the University of Massachusetts at Amherst. The primary research goal of this project is to measure the amount and radial dependence of star-formation in galaxy clusters as a function of redshift in order to investigate the dominant physical processes that affect star formation and galaxy evolution in cluster environments. She is developing a technique to use narrow-band, near-infrared imaging to derive star-formation rates for these distant galaxies from the H-alpha emission of ionized hydrogen. The project will target galaxy clusters between redshifts of 0.5 and 0.8. In addition to her research, Dr. Finn will design and teach a project-based undergraduate course on observational techniques consisting of three modules on distance indicators. One module on Cepheid Variables will be adapted for use by high-school students and will be transferred to teachers through an existing teacher-training program. ***
