TL;DR: In this paper, the authors describe the control of the longitudinal degrees of freedom in the Advanced Virgo instrument during the O2 science run and the process that brought the detector from an uncontrolled, non-resonant state to its target working point.

TL;DR: In this paper , the authors present the results of a model-based search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1 using LIGO detector data from the third observing run of Advanced LIGA and Advanced Virgo.

TL;DR: A detailed method to align a high magnification off-axis afocal parabolic telescope using an initial pre-alignment using autocollimators, followed by a fine tuning with a collimated laser beam.

TL;DR: The Virgo DetChar group during the O3 run achieved the addition of about 80 events to the catalog of transient gravitational-wave sources maintained by LIGO, Virgo and KAGRA, with a focus on the associated tools and the main prospects for future data-taking periods with an improved detector.

TL;DR: In this article , the authors describe a search for gravitational waves from compact binary black holes with at least one component with mass 0.2 and mass ratio q ≥ 0.1 in Advanced LIGO and Advanced Virgo data collected between 1 November 2019 and 27 March 2020, 17:00 UTC.
