论文摘要
我们介绍了全天搜索连续重力波信号的结果，其频率在1700-2000 Hz的范围内，从椭圆度为1E-8的中子星。该搜索在Ligo O2公共数据上采用了猎鹰分析管道[引用5]。我们的结果提高了一个超过5的因素[引用11]。这是一个巨大的飞跃：需要全新的引力波检测器才能使上一代人提高10倍的灵敏度[引用12]。在探测的频率范围内，除了检测到的离群值外，我们可以在地球65 pc内排除椭圆度1E-8的中子星。我们在重力波幅度上设置了上限，即使对于最坏情况下的信号参数也可以。发现了新的异常值，其中一些我们无法与任何工具原因联系在一起。如果有任何与旋转中子恒星相关的，那么这可能是当今最快的中子恒星。
We present the results of an all-sky search for continuous gravitational wave signals with frequencies in the 1700-2000 Hz range from neutron stars with ellipticity of 1e-8. The search employs the Falcon analysis pipeline [citation 5] on LIGO O2 public data. Our results improve by a factor greater than 5 over [citation 11]. This is a huge leap forward: it takes an entirely new generation of gravitational wave detectors to achieve a 10-fold sensitivity increase over the previous generation [citation 12]. Within the probed frequency range and aside from the detected outliers, we can exclude neutron stars with ellipticity of 1e-8 within 65 pc of Earth. We set upper limits on the gravitational wave amplitude that hold even for worst-case signal parameters. New outliers are found, some of which we are unable to associate with any instrumental cause. If any were associated with a rotating neutron star, this would likely be the fastest neutron star today.
