The Laser Interferometer Gravitational-Wave Observatory (LIGO)'s goal is the direct detection of gravitational waves from various astrophysical sources to open a totally new window on the Universe. LIGO's widely separated interferometers are used in coincidence to search for gravitational waves emitted by compact binary systems, spinning neutron stars, supernovae and other cosmological phenomena. The LIGO detectors are now approaching design performance and prolonged data taking will commence in late 2005. Development of a more sensitive advanced detector is already well underway. The scientific program of LIGO is the mission of the LIGO Scientific Collaboration (LSC).LIGO's current alternating cycles of data taking, data analysis and detector improvement activities provide an opportunity for the experimental gravity group at Columbia University (GECo) as a new LSC group. The GECo group intends to play a pivotal role in the following critical areas: (1) Timing accuracy and timing diagnostics for LIGO and Advanced LIGO to enable crucial coincidence detection; (2) Improvement, development, and support for detector diagnostic tools and physical environmental monitoring systems needed to improve detector reliability and to quantify data quality; (3) Execution and further development of sensitive and specialized analyses, which take advantage of astrophysical triggers, such as gamma ray bursts and optical supernovae. These activities provide hands-on opportunities for graduate and undergraduate students. The PI will participate in a number of Columbia University programs involving outreach to the local community.

激光干涉仪重力波观测站（Ligo）的目标是直接检测来自各种天体物理学来源的引力波，以打开宇宙的全新窗口。 Ligo广泛分离的干涉仪是巧合的，以寻找由紧凑型二元系统，旋转中子星，超新星和其他宇宙学现象发出的引力波。 Ligo探测器现在正在接近设计性能，并且延长数据将于2005年底开始。开发更敏感的高级检测器已经在进行中。 Ligo的科学计划是Ligo Scientific Collaporation（LSC）的使命。Ligo当前的数据获取周期，数据分析和探测器改进活动为哥伦比亚大学（GECO）的实验重力小组（GECO）作为新的LSC小组提供了机会。 GECO组打算在以下关键领域中发挥关键作用：（1）Ligo和Advanced Ligo的时序准确性和时机诊断，以实现重要的重合检测； （2）改进，开发和支持探测器诊断工具和物理环境监测系统，以提高检测器可靠性并量化数据质量； （3）敏感和专业分析的执行和进一步发展，这些分析利用了天体物理触发器，例如伽马射线爆发和光学超新星。这些活动为研究生和本科生提供了动手的机会。 PI将参加许多涉及向当地社区推广的哥伦比亚大学计划。
