项目摘要

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). Nearly hundred years after the debut of Einstein's theory of general relativity, gravitational waves are viewed as one of the most intriguing but still elusive astrophysical phenomena. They are expected to be emitted by extreme astrophysical sources such as merging black hole binary systems, spinning neutron stars, gamma-ray bursts or supernovae. Superb and finely tuned gravitational-wave telescopes are required for detection and astrophysics investigations. This award will enable members of the Columbia Experimental Gravity group to participate in activities to improve the performance of the LIGO gravitational wave detectors. Group members will focus on mission-critical activities directly affecting the sensitivity of the LIGO Scientific Collaboration's searches for cosmic gravitational waves such as detector diagnostics and calibration. A well characterized and precisely calibrated detector in turn could enable the data analysts to execute searches that see farther, see more, produce fewer false alarms and extract more information from plausible future detections. Students from high school through graduate level will have the opportunity to participate in this research. In addition, the urban setting and existing outreach infrastructure of Columbia University will enable unique educational and outreach activities based on this research that target schools not only in the local community but also in the greater New York City metropolitan area.

该奖项是根据2009年《美国复苏与再投资法》（公法111-5）资助的。爱因斯坦（Einstein）的一般相对论理论首次亮相近百年后，引力波被视为最有趣但仍然难以捉摸的天体物理现象之一。预计它们会被极端的天体物理源发射，例如合并黑洞二元系统，旋转中子星，伽马射线爆发或超新星。进行检测和天体物理研究需要精美，精细的重力波望远镜。该奖项将使哥伦比亚实验重力小组的成员能够参与活动，以提高LIGO重力波探测器的性能。小组成员将专注于直接影响Ligo Scientific Collaboration对宇宙引力波（例如探测器诊断和校准）的敏感性的关键活动。一个良好的特征和精确校准的检测器又可以使数据分析师能够执行搜索，从而看到更多，看到更多，产生更少的错误警报并从合理的未来检测中提取更多信息。高中到研究生一级的学生将有机会参加这项研究。此外，哥伦比亚大学的城市环境和现有的外展基础设施将基于这项研究来实现独特的教育和外展活动，该研究不仅针对当地社区，而且针对大纽约市大都会地区。
