This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The award is for a pilot program to explore two areas related to OH masers: an OH maser survey of the Andromeda galaxy (M 31) to study the dark matter distribution and kinematics in the Local Group, and an OH megamaser survey at redshift ~1 close to the peak of cosmic star formation and black hole growth to study galaxy merging and associated phenomena. The M31 work will try to detect the galaxy's proper motion in order to constrain dark matter halos and the dynamical evolution of the Local Group. The megamaser survey will use the Green Bank Telescope to observe IR-selected galaxies at redshifts z ~ 1. The award is for one year with the aim of obtaining evidence that masers can be detected in the target objects. Broader impacts of the program include research training for undergraduate and graduate students, and utilization of new educational programs and methods in use at the University of Colorado, including K-12 science teacher training and the learning assistant program.

该奖项是根据2009年《美国复苏和再投资法案》(公法111-5)提供资金的。该奖项是为了探索两个与OH脉泽相关的领域的试点计划：对仙女座星系(M31)的OH脉泽调查，以研究本星系群中的暗物质分布和运动学，以及在接近宇宙恒星形成和黑洞增长峰值的红移~1处的OH兆泽调查，以研究星系合并和相关现象。M31的工作将试图探测星系的自行，以限制暗物质晕和局部群的动力学演化。超级激光探测将使用绿岸望远镜来观测红移为z~1的红外精选星系。该奖项为期一年，目的是获得在目标天体中可以探测到脉泽的证据。该计划的更广泛影响包括为本科生和研究生提供研究培训，以及利用科罗拉多大学正在使用的新教育计划和方法，包括K-12科学教师培训和学习助理计划。
