高级LIGO引力波观测站的审查导致观测运行4

Review of the Advanced LIGO gravitational wave observatories leading to observing run four

Craig Cahillane, Georgia Mansell

摘要:

来自双黑洞和中子星合并的引力波正被定期探测到。截至2021年,LIGO和Virgo探测器已经进行了90次有把握的引力波探测。目前正在进行工作,以进一步提高第四次观测运行的探测器的灵敏度,包括安装一些A+升级,旨在降低限制引力波灵敏度的基本噪声。在这篇综述中,我们将概述LIGO探测器的工作原理,包括它们的光学配置和锁定获取过程,讨论探测器的基本和技术噪声限制,并与当前测量的灵敏度进行比较,并回顾目前正在安装在探测器中的A+升级。

英文摘要:

Gravitational waves from binary black hole and neutron star mergers are being regularly detected. As of 2021, ninety confident gravitational wave detections have been made by the LIGO and Virgo detectors. Work is ongoing to further increase the sensitivity of the detectors for the fourth observing run, including installing some of the A+ upgrades designed to lower the fundamental noise that limits the sensitivity to gravitational waves. In this review, we will overview how the LIGO detectors work, including their optical configuration and lock acquisition procedure, discuss the detectors' fundamental and technical noise limits and compare to the current measured sensitivity, and review the A+ upgrades currently being installed in the detectors.
