This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Dr. Geoffrey Bower of the University of California Berkeley will undertake an extensive survey of static and variable sources at radio wavelengths, using the new Allen Telescope Array. The new survey is called the Five GHz Sky Survey (FiGSS), and will cover about 10,000 square degrees (one-third of the radio sky). It will also include cross-comparisons with surveys at optical and other wavelengths. This static survey will be considerably more sensitive than existing surveys. Two smaller fields (100 and 10 square degrees) will be observed with rapid cadence (every 10 days and daily, respectively). The goals of the transient survey include systematic search for radio supernovae in nearby galaxies; discovery of orphan gamma-ray burst afterglows, the predicted counterparts to otherwise unobservable stellar explosions; discovery of radio emission from tidal disruption of stars by massive black holes; and detection of stellar-mass black hole eruptions and dwarf star outbursts. Many of these phenomena have not been characterized in a systematic way to date. Research on FiGSS will be conducted by a small group centered at Berkeley, including postdoctoral fellows, and graduate and undergraduate students, providing valuable training for the next generation of astronomers. The results of FiGSS will be disseminated to the larger community through the Virtual Observatory.

该奖项是根据2009年《美国回收与再投资法》（公共法第111-5）.DR资助的。加州大学伯克利分校的杰弗里·鲍尔（Geoffrey Bower）将使用新的艾伦望远镜阵列对无线电波长进行广泛的静态和可变来源调查。 这项新调查称为“五GHz天空调查（无花果”），将覆盖约10,000平方英尺（占广播天空的三分之一）。 它还将包括在光学和其他波长下进行调查的跨综合子。 这项静态调查将比现有调查更敏感。 将观察到两个较小的场（100和10平方度），快速节奏（分别每天和每天）。 瞬态调查的目标包括系统地搜索附近星系中的无线电新星；发现孤儿伽玛射线爆发后，预测的对应物是其他不可观察的恒星爆炸；通过巨大的黑洞发现恒星的潮汐破坏，从而发现无线电发射；并发现恒星质量的黑洞爆发和矮星爆发。迄今为止，这些现象中的许多现象尚未以系统的方式进行表征。关于无花果的研究将由一个以伯克利为中心的小组进行，包括博士后研究员以及研究生和本科生，为下一代天文学家提供宝贵的培训。无花果的结果将通过虚拟天文台传播到更大的社区。
