Advanced Virgo Plus for O5 -- Design Report Overview
F. Acernese, A. Agapito, D. Agarwal +578
This document presents an overview of the design, implementation, and expected performance of the Advanced Virgo Plus (AdV+) upgrades in view of the O5 observing run. Following the…
Reducing the Virgo site infrastructure noise in preparation of the O4 observing run
Irene Fiori, Federico Paoletti, Roberto Passaquieti +5
The heating, ventilation and air conditioning systems serving the experimental halls of the Virgo gravitational wave interferometer generate low-frequency noise - namely below 100…
Characterization of the seismic field at Virgo and improved estimates of Newtonian-noise suppression by recesses
Ayatri Singha, Jan Harms, Stefan Hild +10
Fluctuations of gravitational forces cause so-called Newtonian noise (NN) in gravitational-wave (GW) detectors which is expected to limit their low-frequency sensitivity in upcomin…
The KAGRA underground environment and lessons for the Einstein Telescope
Francesca Badaracco, Camilla De Rossi, Irene Fiori +6
The KAGRA gravitational-wave detector in Japan is the only operating detector hosted in an underground infrastructure. Underground sites promise a greatly reduced contribution of t…
Machine learning for gravitational-wave detection: surrogate Wiener filtering for the prediction and optimized cancellation of Newtonian noise at Virgo
F Badaracco, J Harms, A Bertolini +9
The cancellation of noise from terrestrial gravity fluctuations, also known as Newtonian noise (NN), in gravitational-wave detectors is a formidable challenge. Gravity fluctuations…
Seismic array measurements at Virgo's West End Building for the configuration of a Newtonian-noise cancellation system
M. C. Tringali, T. Bulik, J. Harms +9
Terrestrial gravity fluctuations produce so-called Newtonian noise (NN) which is expected to limit the low frequency sensitivity of existing gravitational-waves (GW) detectors LIGO…
