摘要

引力波是时空中的“涟漪”，是由宇宙中一些最剧烈、最具能量的过程引起的。利用激光干涉仪引力波天文台（LIGO）的应变数据对GW150914和GW170104引力波进行了研究。所提出的分析与已发表的有关该主题的结果一致。人们发现，这两个星系都产生了引力波，引力波来自一对在合并前非常接近的黑洞。研究了系统的啁啾质量、致密比、光度距离、偏心率、红移和自旋参数等不同特性，并根据结果识别了系统的性质。

Study of Gravitational Waves GW150914 and GW170104 as a Black Hole Merger

Gravitational waves are ‘‘ripples’’ in space-time caused by some of the most violent and energetic processes in the Universe. A study of gravitational waves GW150914 and GW170104 was carried out using strain data from LIGO (Laser Interferometer Gravitational Wave Observatory). The analysis presented is consistent with the published results on the subject. It was found that both systems produced gravitational waves from a pair of inspiraling black holes that approached very closely before merging. Different properties of the systems like chirp mass, compactness ratio, luminosity distance, eccentricity, redshift, and spin parameter were studied and the nature of the system was identified from the results.
