引力波的预言、探测和发现

The prediction,detection and discovery of gravitational wave

  • 摘要: 引力波是爱因斯坦在广义相对论的重要预言,引力波探测是当代物理学最重要的前沿领域之一。以引力波探测为基础的引力波天文学是一门新兴的交叉科学,是对传统电磁辐射天文学的巨大拓展与补充。文中讨论了引力波的预言和特性,给出了引力波探测的主要方法,详细分析了激光干涉仪引力波探侧器的工作原理和基本结构,介绍了引力波事例GW150914的主要参数和探测、数据处理。

     

    Abstract: Gravitational wave is an important prediction of Einstein's general relativity,The detection of gravitational wave is one of the greatest frontier area of physics. The gravitational wave astronomy based on the gravitational wave detection is a new area of science. It is a big development and complimentary of traditional electromagnetic radiation Astronomy. The prediction,properties and detection of gravitational wave have been discussed, the working principle and basic construction of laser interferometer gravitational wave detector were analyzed. The main parameters of the gravitational wave event GW150914, its detection and the method of data analysis have also been introduced.
