Advanced Virgo during the LIGO-Virgo-KAGRA fourth observing run
Virgo Collaboration, F Acernese, A Agapito +546
The paper reports on Advanced Virgo's participation in the fourth observing run (O4) of the global gravitational‑wave detector network, describing the commissioning of its new sign…
BinaryGFH-v2: Improved method to search for gravitational waves from sub-solar-mass, ultra-compact binaries using the Generalized Frequency-Hough Transform
Andrew L. Miller, Lorenzo Pierini
Observing gravitational waves from sub-solar-mass, inspiraling compact binaries would provide almost smoking-gun evidence for primordial black holes. Here, we develop a method to s…
GFH-v2 Pipeline for Searches of Long-Transient Gravitational Waves from Newborn Magnetars
Sandhya Sajith Menon, Lorenzo Pierini, Pia Astone +11
This paper presents an enhanced methodology for searching long transient gravitational waves associated with a newborn magnetar, with particular focus on the regime in which the ea…
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…
py5vec: a modular Python package for the 5-vector method to search for continuous gravitational waves
Luca D'Onofrio, Federico Muciaccia, Lorenzo Mirasola +7
We present \texttt{py5vec}, a Python package for implementing and extending the 5-vector method, used to search for continuous gravitational wave (CW) signals. We also provide a co…
