Progress in gravitational-wave astronomy depends upon having sensitive
detectors with good data quality. Since the end of the LIGO-Virgo-KAGRA third
Observing run in March 2020, detector-characterization efforts have lead to
increased sensitivity of the detectors, swifter validation of
gravitational-wave 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 gravitational-waves. 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.
