Signatures of Galaxy Evolution in Groups at z ~ 1

AST-0302153 Metevier，AnneDr.Metevier被授予NSF天文学和天体物理学博士后奖学金，在加州大学圣克鲁斯分校的自适应光学中心(CFAO)开展研究和教育计划。她的研究将集中于描述遥远星系群的特征，目的是促进我们对支配星系演化的物理过程的理解。在高红移时，星系群本质上是一种未被探索的密度制度，但它们是我们理解星系演化的关键，因为它们弥合了相对研究较好的星系团和场环境之间的密度差距。梅特维耶博士将定义红移约为1的星系群目录，然后测量组成星系的质量、结构参数和恒星形成特征。然后，她将通过与理论预测的比较，将这些测量结果与可能影响它们的物理过程联系起来。梅特维耶博士还将与未被充分代表的社区大学学生合作。她将在当地一所为少数民族服务的机构哈特内尔学院开发和教授天文实验室短期课程，目的是为学生提供与CFAO研究高度相关的知识基础和经验。在短期课程之外，她将继续通过CFAO的结对指导计划为学生提供建议，并招募他们参加CFAO的暑期实习计划。***

AST-0302153Metevier, AnneDr. Metevier is awarded an NSF Astronomy and Astrophysics Postdoctoral Fellowship to carry out a program of research and education at the Center for Adaptive Optics (CfAO) at the University of California, Santa Cruz. Her research will focus on characterizing the galaxy populations of distant groups with the goal of advancing our understanding of the physical processes that govern galaxy evolution. At high redshifts, galaxy groups are essentially an unexplored density regime, yet they are key to our understanding of galaxy evolution, as they bridge the density gap between the comparatively well-studied galaxy cluster and field environments. Dr. Metevier will define a catalog of galaxy groups at a redshift of about 1, and then measure constituent galaxies' masses, structural parameters, and star formation characteristics. She will then relate these measurements to the physical processes which may be affecting them by comparison with theoretical predictions. Dr. Metevier will also work with under-represented community college students. She will develop and teach an astronomy laboratory short course at Hartnell College, a local minority-serving institution, with the goal of providing students with a knowledge base and experiences highly relevant to CfAO research. Beyond the short course, she will continue to advise the students through the CfAO's Paired Mentoring Program and recruit them for the CfAO's Summer Internship Program. ***
