Searches for gravitational waves with coherent network algorithms

将开展一项多方面的高级研究方案，以利用在世界各地运行的干涉探测器网络搜索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，将开发和应用相干数据分析方法来寻找非触发引力波爆发的特定来源。特别是，将开发和执行以检测来自二元黑洞系统的合并信号为目标的搜索。第二，将为外部触发的GW辐射源制定相干检测战略。寻找与伽马射线暴有关的引力波是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区域提供关于相对论引力的丰富信息。LIGO是有史以来进行的最先进的实验努力之一。它复杂的设计和复杂的数据分析为学生在物理的各个领域提供了绝佳的教育和研究机会。在这个项目中，他们将涉及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以及现代天体物理理论。该研究计划利用全球引力波探测器网络解决引力波探测问题。参与与多国团队合作进行的联合数据分析将使学生获得独特的研究体验，并接触到开展研究和追求科学的不同文化方法。因此，这将使他们能够为广泛的职业机会做准备并获得这些机会。

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.
