LIGO and Virgo detector characterization and data quality: Contributions to the O3 run and preparation for O4

Résumé

Only a few years after the first direct detections by LIGO and Virgo, the gravitational-wave (GW) field is at a turning point, with a rapidly increasing number of confirmed signals. This progress is made possible by the improvements in sensitivity and duty cycle of the second-generation ground-based GW detectors, such as by advances in the analysis of the recorded data. Key to this dataflow are the detector characterization and data quality studies, collectively referred to as “DetChar” in these proceedings. The former set of activities helps improve the knowledge of the instruments while fighting against their dominant noise sources (transient or continuous). The latter one shapes the dataset for the analyses, vets the GW candidates found either in low latency or offline, and contributes to mitigating the effect of noise when inferring the GW source properties from the detected signals. In these proceedings, the LIGO and Virgo DetChar groups summarize their main contributions to the GW detection effort during the third Observing Run (O3, April 2019–March 2020). We also describe the main developments and improvements which are in progress to cope with the increase in detection rate expected for the fourth LIGO-Virgo-KAGRA Observing Run (O4).
