Probing Strong Gravity Gravitational Waves

项目摘要

Gravitational wave astrophysics is entering a new era of discovery and exploration, with first detections expected within the next few years with Advanced LIGO. One of the key missions of the LIGO project is to test Einstein's theory of General Relativity where it has never been tested before: where the gravitational forces are enormous compared to those found in the solar system. Such a task is achievable because gravitational waves encode information about the strong gravitational forces present when black holes and neutron stars collide to produce gravitational waves. This award supports a research program to develop and implement a generic and model-independent framework to test Einstein's theory of General Relativity and to search for anomalous deviations from it in gravitational wave data. The necessary tools to achieve this objective will be developed and implemented, so that they can be readily deployed in LIGO.The research will enable exploitation of the full discovery potential of gravitational wave detection. This type of research is also timely and relevant, in view of upcoming, advanced detectors and the dawn of gravitational wave astrophysics. While the detection of a departure from Einstein's predictions could signal transformative new physics, the absence of such departures could provide strong confirmation for general relativity in an as yet untested regime.

引力波天体物理学正在进入一个发现和探索的新时代，预计在未来几年内将通过先进的LIGO进行首次探测。LIGO项目的关键任务之一是测试爱因斯坦的广义相对论，这是以前从未测试过的：与太阳系中发现的引力相比，引力是巨大的。这样的任务是可以实现的，因为当黑洞和中子星碰撞产生引力波时，引力波编码了关于强引力的信息。该奖项支持一项研究计划，以开发和实施一个通用的和模型无关的框架，以测试爱因斯坦的广义相对论，并在引力波数据中寻找异常偏差。将开发和实施实现这一目标的必要工具，以便它们可以随时部署在LIGO中。这项研究将使引力波探测的全部发现潜力得到充分利用。鉴于即将到来的先进探测器和引力波天体物理学的曙光，这种类型的研究也是及时且相关的。虽然检测到偏离爱因斯坦的预测可能标志着变革性的新物理学，但没有这种偏离可能在尚未测试的情况下为广义相对论提供强有力的证实。
