项目摘要

The Oregon group will continue its vigorous efforts aimed at discovery of gravitational waves with Advanced LIGO, working within the LIGO Scientific Collaboration (LSC). However, most importantly for the next three years, the Oregon group will apply to Advanced LIGO the deep expertise gained from the initial LIGO experience in detector characterization. In particular, our leadership in finding, describing, and mitigating noise sources which are not intrinsic to the LIGO interferometers will be crucial to the success of Advanced LIGO. And it is during this period of transition, as the new systems are being installed and commissioned, that these investigations will be most valuable. This will be carried out via two main avenues of inquiry: (1) detector characterization, and (2) data analysis, especially in developing strategies to search for gravitational wave transients associated with astrophysical triggers, such as gamma-ray bursts (GRBs) or supernovae. For detector characterization, the focus will be to interrogate Advanced LIGO sub-systems as they come on line. We will identify potentially problematic couplings of the LIGO interferometers to noise from the environment (electromagnetic, seismic, acoustic, cosmic-ray, etc), determine the physical character of the coupling, and use this knowledge to reduce or mitigate it. In data analysis and gravitational wave science, the Oregon group plans to continue to play a central role in developing strategies and analyses to search for astrophysically-triggered, transient gravitational wave signals. The overriding goal is to be ready with a full arsenal of analysis tools, including infrastructure to provide timely communication with astronomical partners, when Advanced LIGO begins science running. And as LIGO makes the transition from a discovery phase to a full program of gravitational wave science, the Oregon group will be poised to exploit the rich scientific opportunities available.During the next three years, the quest for the discovery of gravitational waves -- a fundamental natural phenomenon predicted by Einstein's General Relativity -- will enter a critical phase. The LIGO project is transitioning to its "advanced" phase. Advanced LIGO, when complete in about three years, is expected to have the exquisite sensitivity required to directly detect gravitational wave signals for the first time. This discovery, when realized, will usher in a new era of astronomy and astrophysics, as gravitational waves will provide a unique view of the cosmos, distinct from that provided by light, radio, x-rays, gamma rays, neutrinos, or other astronomical messengers.
俄勒冈州的研究小组将继续在LIGO科学合作组织(LSC)的框架下,积极致力于利用先进的LIGO发现引力波。然而,最重要的是,在接下来的三年里,俄勒冈团队将把从最初的LIGO探测器表征经验中获得的深厚专业知识应用到Advanced LIGO中。特别是,我们在寻找、描述和减轻非LIGO干涉仪固有噪声源方面的领导作用,将对高级LIGO的成功至关重要。正是在这个过渡时期,随着新系统的安装和投入使用,这些调查将是最有价值的。这将通过两个主要的调查途径进行:(1)探测器表征,(2)数据分析,特别是在制定策略以搜索与天体物理触发相关的引力波瞬变,如伽马射线暴(GRBs)或超新星。对于探测器的特性,重点将是询问先进的LIGO子系统,因为它们已经上线。我们将确定LIGO干涉仪与环境噪声(电磁、地震、声学、宇宙射线等)之间可能存在的耦合问题,确定耦合的物理特性,并利用这些知识来减少或缓解这种耦合。在数据分析和引力波科学方面,俄勒冈小组计划继续在开发策略和分析方面发挥核心作用,以寻找由天体物理学触发的瞬态引力波信号。最重要的目标是准备好完整的分析工具库,包括基础设施,以便在Advanced LIGO开始科学运行时及时与天文合作伙伴进行通信。随着LIGO从发现阶段过渡到引力波科学的完整项目,俄勒冈团队将准备好利用丰富的科学机会。在接下来的三年里,寻找引力波——爱因斯坦广义相对论预言的一种基本自然现象——的探索将进入一个关键阶段。LIGO项目正在过渡到“高级”阶段。先进的LIGO将在大约三年内完成,预计将具有首次直接探测引力波信号所需的精密灵敏度。这一发现一旦实现,将开启天文学和天体物理学的新时代,因为引力波将提供一个独特的宇宙视角,不同于光、无线电、x射线、伽马射线、中微子或其他天文信使所提供的视角。
