Dr. Eilat Glikman is awarded an NSF Astronomy and Astrophysics Postdoctoral Fellowship to carry out a program of research and education at Yale University. Dr. Glikman will study the role of dust-obscured quasars in relation to the overallquasar population. Dust-obscured quasars are a newly discovered and thoroughly unexplored stage of quasar evolution and may represent a missing link in the path from nascent active galactic nuclei seen buried in merging ultraluminous infrared galaxies (ULIRGs) to quasars that show no signs of disruption. Dr. Glikman will (1) conduct several new surveys for dust-obscured quasars increasing the depth and area beyond existing surveys to determine their fraction in the overall quasar population and study their reddening properties as functions of luminosity and redshift and (2) use integral-field spectroscopy to study their dynamics at subarcsecond resolutions.Dr. Glikman will also utilize her extensive experience with outreach and mentorship in a multi-pronged education effort. She will develop and teach a modern cosmology course geared towards advanced undergraduate students. In addition, she will take advantage of the Yale-New Haven Teachers Institute to pair with a local middle school science teacher to conduct hands-on astronomy activities during the school year and in intensive summer workshops. Dr. Glikman will also design a self-contained project from within the scope of the her research and work directly with undergraduate science students, with a focus on providing mentorship to women scientists. This individualized approach of fostering stimulating collegial relationships between women scientists emphasizes the importance of role models and mentors to improve the confidence and success of women in the field of astronomy.

埃拉特·格里克曼博士被授予美国国家科学基金会天文学和天体物理学博士后奖学金，在耶鲁大学开展研究和教育项目。格里克曼博士将研究被尘埃遮挡的类星体与整体类星体数量之间的关系。被尘埃遮挡的类星体是类星体演化的一个新发现和完全未被探索的阶段，可能代表着从埋藏在合并的超发光红外星系(ULIRG)中的新生活动星系核到没有显示出分裂迹象的类星体的路径上缺失的一环。格里克曼博士将(1)对尘埃遮挡的类星体进行几次新的调查，在现有调查的基础上增加深度和面积，以确定它们在类星体总数中的比例，并研究它们随着光度和红移的函数而变红的特性，以及(2)使用积分场光谱学来研究它们在亚弧秒分辨率下的动力学。格里克曼还将利用她在外展和指导方面的丰富经验，进行多管齐下的教育努力。她将开发并教授一门面向高级本科生的现代宇宙学课程。此外，她还将利用耶鲁-纽黑文师范学院的优势，在学年期间与当地一名中学科学教师结对开展实践天文活动，并在密集的暑期工作坊中开展活动。格里克曼博士还将在她的研究范围内设计一个自给自足的项目，直接与理科本科生合作，重点是为女性科学家提供指导。这种促进女科学家之间激动人心的合作关系的个人化方法强调了榜样和导师对提高妇女在天文学领域的信心和成功的重要性。
