Dr. Karin Menendez-Delmestre is awarded an NSF Astronomy and Astrophysics Postdoctoral Fellowship to carry out a program of research and education at the Observatories of the Carnegie Institution of Washington. Dr. Menendez-Delmestre will conduct a multi-wavelength study of proto-clusters at high redshift that will use submillimeter galaxies as signposts of these large-scale structures. The aim of the program will be to investigate the relationship between galaxy properties and their proto-cluster environment.The morphology-density relation, which particularly addresses the distribution of galaxy morphologies within clusters, has been established at z 1. Dr. Menendez-Delmestre will extend current knowledge of galaxy evolution as a function of environment to incorporate other galaxy properties (morphologies, sizes, star-formation rates, stellar ages, stellar masses, metallicities, outflows and active galactic nuclei activity) and to extend the study out to the higher redshifts traced by submillimeter galaxies, z ~ 1-3. Major components to this research are detailed spectroscopic and photometric observations of individual proto-cluster members using Persson's Auxilliary Nasmyth Infrared Camera (PANIC) and the Inamori Magellan Areal Camera and Spectrograph (IMACS) on the Magellan Telescope.Dr. Menendez-Delmestre will also extend Carnegie's commitment to outreach and education towards a broader section of the Los Angeles community by strengthening the existing, yet informal ties with the Griffith Observatory, a well recognized leader in the Los Angeles community as a center of public education. With a Hispanic population greater than 50%, Los Angeles is an exceptionally well suited area to develop educational outreach programs that specifically target the Hispanic community. Dr. Menendez-Delmestre will serve as a Curatorial Advisor to the Griffith program team led by Dr. Laura Danly (Curator, Griffith Observatory) by: (1) helping in the implementation of a Griffith school astronomy program directed at elementary-school children; (2) training Observatory guides; (3) reviewing the accuracy of the Observatory's educational materials; and (4) helping to organize public, astronomy-related activities at Griffith.

Karin Menendez-Delmestre博士被授予NSF天文学和天体物理学博士后奖学金，在华盛顿卡内基研究所的天文台开展研究和教育计划。Menendez-Delmestre博士将对高红移的原星系团进行多波长研究，该研究将使用亚毫米星系作为这些大尺度结构的路标。该计划的目的是研究星系的性质和它们的原星系团环境之间的关系。形态密度关系，特别是解决星系团内的星系形态分布，已建立在z 1。Menendez-Delmestre博士将扩展目前关于星系演化作为环境函数的知识，以纳入其他星系特性（形态，大小，恒星形成率，恒星年龄，恒星质量，金属丰度，外流和活动星系核活动），并将研究扩展到亚毫米星系z ~ 1-3的较高红移。这项研究的主要组成部分是使用麦哲伦望远镜上的纳史密斯红外照相机（PANIC）和稻盛麦哲伦区域照相机和光谱仪（IMACS）对单个原星团成员进行详细的光谱和光度观测。梅嫩德斯-德尔梅斯特博士还将通过加强现有的，然而，与格里菲斯天文台，一个公认的领导者在洛杉矶社区作为一个公共教育中心的非正式关系。随着西班牙裔人口超过50%，洛杉矶是一个非常适合的地区，以发展教育推广计划，专门针对西班牙裔社区。Menendez-Delmestre博士将担任由Laura Danly博士领导的格里菲斯项目团队的策展顾问（格里菲斯天文台馆长）通过：（1）帮助实施针对小学生的格里菲斯学校天文学计划;（2）培训天文台导游;（3）审查天文台教育材料的准确性;以及（4）帮助在格里菲斯组织与天文学有关的公共活动。
