LIGO探测器瞬态噪声特性

Characterising Transient Noise in the LIGO Detectors

L. K. Nuttall

摘要:

来自LIGO探测器的数据通常包含许多由于仪器和环境条件而产生的非高斯噪声瞬态。这些非高斯瞬态可能是建模和未建模瞬态引力波搜索的一个问题,因为它们可能掩盖或模仿真实信号。数据质量可能会迅速变化,因此必须跟踪并找到新的瞬态噪声源,以便将数据污染降至最低。瞬态噪声的几个例子和用于跟踪它们的工具。这些实例突出了LIGO探测器在第二次观测运行期间存在的各种噪声源。

英文摘要:

Data from the LIGO detectors typically contain many non-Gaussian noise transients which arise due to instrumental and environmental conditions. These non-Gaussian transients can be an issue for the modelled and unmodelled transient gravitational-wave searches, as they can mask or mimic a true signal. Data quality can change quite rapidly, making it imperative to track and find new sources of transient noise so that data are minimally contaminated. Several examples of transient noise and the tools used to track them are presented. These instances serve to highlight the diverse range of noise sources present at the LIGO detectors during their second observing run.
