A multi-faceted program of advanced research will be conducted to search for bursts of gravitational waves from anticipated astrophysical sources with the network of interferometric detectors operating around the world. Research and development for LIGO data analysis will be carried out in two main areas. First, coherent data analysis methods will be developed and applied to search for specific sources of un-triggerd gravitational wave bursts. In particular, searches which target detection of merger signals from binary black hole systems will be developed and executed. Second, coherent detection strategies will be developed for externally triggered sources of GW radiation. Searches for gravitational waves associated with Gamma Ray Bursts will be conducted.The search for gravitational waves from binary sources is one of the main goals of the LIGO Project. Once discovered they will provide rich information about relativistic gravity in highly non-linear and highly dynamical regimes. LIGO is one of the most advanced experimental endeavors ever undertaken. Its complex design and sophisticated data analysis provide fantastic educational and research opportunities for students in all areas of physics. On this project, they will be involved with sophisticated methods for extraction of signals from noise, computational schemes for manipulation of large data sets and modern astrophysical theories. The research program addresses problems of gravitational wave detection with the worldwide network of gravitational wave detectors. Participation in the joint data analyses conducted in collaboration with multinational teams will give students a unique research experience and exposure to the diverse cultural approaches in conducting research and pursuing science. It will thus enable them to prepare for and access a wide spectrum of career opportunities.

将开展一个多方面的高级研究方案，利用在世界各地运行的干涉测量探测器网络，搜寻来自预期天体物理源的引力波爆发。 LIGO数据分析的研究和开发将在两个主要领域进行。 首先，将开发相干数据分析方法并应用于寻找未观测到的引力波爆发的特定来源。 特别是，将开发和执行以探测双黑洞系统合并信号为目标的搜索。第二，将为外部触发的GW辐射源制定相干探测战略。 寻找双星源的引力波是LIGO计划的主要目标之一。一旦被发现，它们将在高度非线性和高度动态的状态下提供关于相对论引力的丰富信息。 LIGO是有史以来最先进的实验努力之一。 其复杂的设计和复杂的数据分析为物理学各个领域的学生提供了绝佳的教育和研究机会。 在这个项目中，他们将参与从噪声中提取信号的复杂方法，处理大型数据集的计算方案和现代天体物理学理论。 该研究计划解决了全球引力波探测器网络的引力波探测问题。 参与与多国团队合作进行的联合数据分析将为学生提供独特的研究体验，并接触到进行研究和追求科学的不同文化方法。 因此，它将使他们能够准备和获得广泛的职业机会。
