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

ast - 0301328 -芬恩,RoseDr。芬恩获得了美国国家科学基金会天文学和天体物理学博士后奖学金，在马萨诸塞大学阿姆赫斯特分校开展研究和教育项目。该项目的主要研究目标是测量星团中恒星形成的数量和径向依赖关系作为红移的函数，以研究影响星团环境中恒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技术，从电离氢的h - α发射中得出这些遥远星系的恒星形成率。该项目将瞄准红移介于0.5和0.8之间的星系团。除了她的研究之外，芬恩博士还将设计和教授一门基于项目的本科课程，该课程包括三个关于距离指示器的模块。造父变星的一个模块将被高中生使用，并将通过现有的教师培训计划转移给教师。* * *

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. ***
