The quantity and quality of observations that we can make with ground-based gravitational-wave detectors depends on three critical tasks: (i) accurately calibrating the detectors; (ii) characterizing the performance of the detectors so that we can improve their astrophysical reach; and (iii) using calibration and data-quality information in both searches and parameter measurement. The...

Accurate calibration of the output of the Gravitational Wave (GW) signal is crucial to determine the physics parameters of the sources. Also in the situation of global detector network, a less relative biases between these detectors are important on the science of GW astronomy. LIGO, Virgo and KAGRA employ the photon calibrator that can calibrate the absolute displacement of the test mass...

Searches for GW from compact binary mergers using waveform templates have already successfully detected several binary black hole signals and are set to yield further discoveries as the network of Advanced detectors matures. We describe how the binary search pipelines used by LIGO-Virgo have broadened the range of systems they target, while becoming more robust against detector noise and thus...

Current matched-filter searches for binary mergers make several simplifying assumptions about the physics of the target systems. For example, the effect of orbital precession is neglected in current searches of advanced-detector data. This can reduce the ability to detect systems that could tell us about the evolution of massive stars and tests of relativity in extreme situations. In this talk...
