The Observations of Redshift Evolution in Large Scale Environments (ORELSE) Survey

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。鲁宾博士将使用10米凯克望远镜上的多目标光谱仪测量20个遥远星系团及其周围星系的红移（远离观测者的运动速度）。 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。 无线电和X射线观测将揭示哪些星系有活跃的核。 该项目的目的是探索60亿至90亿年前这段时期内星系本身、星系团和周围大规模结构之间的联系，当时像我们银河系这样的星系正在非常活跃地形成它们的恒星。研究生和本科生将通过参与研究来进行培训。 卢宾博士在与女学生和代表性不足的群体合作方面有着良好的记录。 在研究过程中收集的大型数据库对其他工作者应该非常有用，并将成为高年级天体物理学课程互动教程的基础。

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.
