我们提出了一个全天空搜索连续引力波（CW）的结果，它可以由快速旋转的中子星产生，围绕其旋转轴的不对称性，使用先进的LIGO探测器的第二次观测运行的数据。我们采用三种不同的半相干方法（$\textit{FrequencyHough}$、$\textit{SkyHough}$和$\textit{Time-Domain $\mathcal{F}$-statistic}$）在20到1922 Hz的引力波频带和$-1\times10^{-8}$到$2\times10^{-9}$ Hz/s的一阶频率导数中进行搜索。这些搜索都没有发现CW信号的明确证据，因此我们提出了引力波应变振幅的上限h_0 $（在123-124 Hz区域，h_0 $的最低上限为1.7\times10 ^{-25}$），并讨论了这一结果的天体物理意义。这是在本研究中探索的广泛参数范围内进行的最敏感的检索。
We present results of an all-sky search for continuous gravitational waves (CWs), which can be produced by fast-spinning neutron stars with an asymmetry around their rotation axis, using data from the second observing run of the Advanced LIGO detectors. We employ three different semi-coherent methods ($\textit{FrequencyHough}$, $\textit{SkyHough}$, and $\textit{Time-Domain $\mathcal{F}$-statistic}$) to search in a gravitational-wave frequency band from 20 to 1922 Hz and a first frequency derivative from $-1\times10^{-8}$ to $2\times10^{-9}$ Hz/s. None of these searches has found clear evidence for a CW signal, so we present upper limits on the gravitational-wave strain amplitude $h_0$ (the lowest upper limit on $h_0$ is $1.7\times10^{-25}$ in the 123-124 Hz region) and discuss the astrophysical implications of this result. This is the most sensitive search ever performed over the broad range of parameters explored in this study.
