Description
On behalf of the Virgo Collaboration, we present the main environmental noise studies carried out at Virgo in-preparation, during, and after the O4 observing run. These studies aimed at characterising the interferometer environment and assessing the coupling of external disturbances to detector sensitivity. We focus in particular on the impact of wind, on magnetic and vibro-acoustic noise coupling measurements, and on mitigation actions applied to infrastructure devices. The results contribute to improving detector robustness and informing future observing runs.
