A Search for Gravitational Radiation at LIGO: Oregon Experimental Relativity Group

俄勒冈州实验相对论研究计划旨在寻找引力波(GWB)的爆发源。实现这一重大科学发现的一个重要前提是识别和改进LIGO干涉仪中的噪声源。处理这些来源是俄勒冈州努力的主要重点之一，开发针对从仪器效应到天体物理调查等一系列问题的数据分析工具也是如此。总体努力可分为四个方面：1.识别和减少环境影响，以提高干涉仪的灵敏度并降低单个干涉仪的误检率。这涉及到确定来源、减少耦合和帮助产生基于环境的否决权。除了环境耦合外，这还包括用于产生否决权的辅助干涉仪通道和重力波通道之间的耦合。2.)研究并在可能的情况下降低三个LIGO干涉仪之间的假符合率。这将涉及继续进行站点间环境对比项目，并调查任何降低噪声与两个汉福德干涉仪的统计独立性的现象。3.)开发和应用数据分发、监测和天体物理分析工具。在LIGO工程和科学运行期间发挥的积极作用将继续下去。4.)将从初始LIGO学到的经验应用到高级LIGO的计划和准备中。俄勒冈州小组的研究通过为扩大影响所做的一些努力，对外部社会作出了重大贡献。这些措施包括本科生参与该小组的研究活动，为有才华的高中生提供暑期研究计划，与俄勒冈州高中教师合作，将研究经验带到高中(夸克网络计划的一部分)，以及向社区团体发表演讲。这项研究还将通过发表科学成果，以及对参与该项目的研究生和博士后助理的教育，为更广泛的社会利益做出贡献。

The Oregon experimental relativity research program is aimed at the search for burst sources of gravity waves (GWBs). An important prerequisite to the realization of this significant scientific discovery is identification and amelioration of noise sources in the LIGO interferometers. Dealing with these sources is one principal focus of the Oregon effort, as is the development of data analysis tools directed at a range of issues from instrumental effects to astrophysical investigations. The overall effort can be categorized into four areas: 1.) identifying and reducing environmental influences, in order to improve interferometer sensitivity and decrease false detection rates for the individual interferometers. This involves identifying sources, reducing coupling and helping produce environmentally based vetoes. In addition to environmental coupling, this involves coupling between auxiliary interferometer channels and the gravity-wave channel for veto production purposes. 2.) studying and, where possible, reducing the false coincidence rates between the three LIGO interferometers. This will involve a continuation of the inter-site environmental correlations project and an investigation of any phenomena which reduces the statistical independence of noise from the two Hanford interferometers. 3.) developing and applying data distribution, monitoring and astrophysical analysis tools. The active role developed during the LIGO engineering and science runs will continue. 4.) applying the lessons learned with Intial LIGO to the plans and preparation for Advanced LIGO. The research of the Oregon group contributes significantly to the outside community through a number of efforts undertaken to broaden the impact. These include undergraduate participation in the group's research activities, summer research programs for talented high school students, work with Oregon high school teachers to bring the research experience into the high school (part of the Quark Net program), and speaking engagements to community groups. This research will also contribute to the broader benefit of society through the publication of the scientific results, and the education of the graduate students and postdoctoral associates working on the project.
