先进的LIGO探测器最近成功地完成了第二次观测运行。这一运行持续了大约10个月，并导致了多项新发现。对引力波的灵敏度部分地受到激光噪声的限制。在这里，我们利用辅助传感器来见证这些相关的噪声源，并使用它们在时域数据中进行噪声相减。这种噪声和线条的去除对于LIGO汉福德天文台来说尤其重要，那里的灵敏度提高了20%以上。因此，我们还能够改进对引力波前体的位置、质量、自转和轨道参数的天体物理估计。
The Advanced LIGO detectors have recently completed their second observation run successfully. The run lasted for approximately 10 months and led to multiple new discoveries. The sensitivity to gravitational waves was partially limited by laser noise. Here, we utilize auxiliary sensors that witness these correlated noise sources, and use them for noise subtraction in the time domain data. This noise and line removal is particularly significant for the LIGO Hanford Observatory, where the improvement in sensitivity is greater than 20%. Consequently, we were also able to improve the astrophysical estimation for the location, masses, spins, and orbital parameters of the gravitational wave progenitors.
