论文摘要
我们介绍了对连续重力波信号的全天搜索结果，其频率为500-1700 Hz范围的靶向中子星，椭圆度为1E-8。使用Falcon Analysis Pipeline对LiGO O2数据进行搜索。此处介绍的结果将灵敏度倍于相同数据的任何其他结果。该搜索能够检测到低至170 pc的低椭圆源。我们建立了严格的上限，这些限制适用于最差的信号参数。我们列出了搜索发现的异常值，其中包括我们无法与任何已知工具原因相关联的几个。
We present the results of an all-sky search for continuous gravitational wave signals with frequencies in the 500-1700 Hz range targeting neutron stars with ellipticity of 1e-8. The search is done on LIGO O2 data using the Falcon analysis pipeline. The results presented here double the sensitivity over any other result on the same data. The search is capable of detecting low ellipticity sources up to 170 pc. We establish strict upper limits which hold for worst-case signal parameters. We list outliers uncovered by the search, including several which we cannot associate with any known instrumental cause.
