摘要

提出了双黑洞并合引力波唯一配准的系统谱分析结果。2015年9月14日，世界标准时间09:50:45，位于美国的激光干涉仪引力波天文台的两个探测器同时观测到一个瞬态引力波信号。这是第一次直接探测到引力波，也是第一次直接观察到双黑洞系统合并形成一个黑洞。利用系统谱分析方法，对引力波信号的时频结构进行了详细的研究。该信号被归类为平均频率变化的超宽带过程。

Gravitational waves as the unique ultra-wideband process

The results of system spectral analysis of the unique registration of the gravitational waves generated by a binary black hole merger were proposed. On September 14, 2015 at 09:50:45 UTC two detectors of the Laser Interferometer Gravitational-Wave Observatory placed in the United States simultaneously observed a transient gravitational-wave signal. These were the first direct detection of gravitational waves and the first direct observation of a binary black hole system merging to form a single black hole. Using the system spectral analysis method, the time-frequency structure of the gravitational wave signal was investigated in detail. This signal was found to be classified as an ultra-wideband process with changing mean frequency.
