This award supports activities related to analysis of the data collected by the Laser Interferometer Gravitational-wave Observatory (LIGO). Three lines of work are being supported: Calibration of the output of the LIGO instruments---a fundamental first step in the search for gravitational waves, searches for gravitational waves from neutron stars, and searches for gravitational waves from cosmic strings.The existence of gravitational waves is one of Einstein's most extraordinary predictions. The direct detection of gravitational waves will usher in a new era in astronomy and dramatically expand our knowledge of the universe. LIGO, a gravitational wave detector of unprecedented sensitivity, is poised to make the first detection. This work will make important contributions to the success of LIGO, and may ultimately lead to the discovery of gravitational waves. A major component of the research activities involves the use of Einstein@Home (which the PI helped to develop) maintained at the University of Wisconsin--Milwaukee. Einstein@Home is a distributed computing effort that harnesses spare CPU cycles from computers around the world to search for gravitational waves in LIGO data. Einstein@Home is an extremely powerful gravitational wave search tool and also an outstanding outreach success, that has brought gravitational wave astronomy to the personal computers of more than 100,000 people around the world.

该奖项支持与分析激光干涉仪引力波天文台(LIGO)收集的数据有关的活动。目前正在支持三项工作：校准LIGO仪器的输出-搜索引力波的基本第一步，搜索来自中子星的引力波，以及搜索来自宇宙弦的引力波。引力波的存在是爱因斯坦最非凡的预测之一。引力波的直接探测将开启天文学的新纪元，并极大地扩展我们对宇宙的认识。LIGO是一种具有前所未有的灵敏度的引力波探测器，即将进行第一次探测。这项工作将为LIGO的成功做出重要贡献，并可能最终导致引力波的发现。研究活动的一个主要组成部分涉及使用威斯康星大学密尔沃基分校维护的爱因斯坦@Home(PI帮助开发)。爱因斯坦@Home是一项分布式计算工作，它利用世界各地计算机的空闲CPU周期来搜索LIGO数据中的引力波。爱因斯坦@Home是一个极其强大的引力波搜索工具，也是一个杰出的外展成功，它已经将引力波天文学带到了世界各地超过10万人的个人电脑上。
