This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Dr. Lubin will use a multi-object spectrograph on the 10-meter Keck telescope to measure redshifts (speed of motion away from the observer) for galaxies in and around 20 distant galaxy clusters. Optical and near-infrared images will be used to map out the distribution of galaxies on scales exceeding 30 million light years. Both the colors of the galaxies and the details of their spectra will be used to probe their star-forming history, and to examine how the pace of starbirth is related to their surroundings. Radio and X-ray observations will reveal which galaxies have active nuclei. The aim is to probe connections between properties of the galaxies themselves, the galaxy clusters, and the surrounding large-scale structure over this period between 6 billion and 9 billion years ago, when galaxies like our Milky Way were very actively forming their stars.Graduate and undergraduate students will be trained through their involvement in the research. Dr. Lubin has a good record of working with women students and those from under-represented groups. The large databases assembled during the research should be very useful to other workers, and will form the basis for interactive tutorials for upper-division astrophysics courses.

该奖项由 2009 年美国复苏和再投资法案（公法 111-5）资助。 Lubin 将使用 10 米凯克望远镜上的多目标摄谱仪来测量 20 个遥远星系团内部及其周围星系的红移（远离观察者的运动速度）。 光学和近红外图像将用于绘制超过 3000 万光年尺度的星系分布图。 星系的颜色和光谱的细节都将被用来探测它们的恒星形成历史，并研究恒星诞生的速度与周围环境的关系。 射电和 X 射线观测将揭示哪些星系具有活动核。 目的是探索 60 亿至 90 亿年前这一时期星系本身、星系团和周围大尺度结构之间的关系，当时像我们银河系这样的星系非常活跃地形成它们的恒星。研究生和本科生将通过参与这项研究来接受培训。 卢宾博士在与女学生和弱势群体学生的合作方面有着良好的记录。 研究过程中收集的大型数据库应该对其他工作者非常有用，并将构成高级天体物理学课程交互式教程的基础。
