Abstract

Progress in gravitational-wave (GW) astronomy depends upon having sensitive detectors with good data quality. Since the end of the Laser Interferometer Gravitational-Wave Observatory-Virgo-KAGRA third Observing run in March 2020, detector-characterization efforts have lead to increased sensitivity of the detectors, swifter validation of GW candidates and improved tools used for data-quality products. In this article, we discuss these efforts in detail and their impact on our ability to detect and study GWs. These include the multiple instrumental investigations that led to reduction in transient noise, along with the work to improve software tools used to examine the detectors data-quality. We end with a brief discussion on the role and requirements of detector characterization as the sensitivity of our detectors further improves in the future Observing runs.

第四次观测运行前半部分的LIGO探测器特性

引力波天文学的进步依赖于具有高质量数据的灵敏探测器。自2020年3月激光干涉仪引力波天文台（virgo - kagra）第三次观测运行结束以来，探测器表征工作已经提高了探测器的灵敏度，更快地验证了GW候选者，并改进了用于数据质量产品的工具。在本文中，我们将详细讨论这些努力及其对我们探测和研究gw能力的影响。其中包括多种仪器调查，以减少瞬态噪声，以及改进用于检查探测器数据质量的软件工具。我们最后简要讨论了探测器特性的作用和要求，因为我们的探测器在未来的观测运行中灵敏度进一步提高。
