Advanced Virgo during the LIGO-Virgo-KAGRA fourth observing run
Virgo Collaboration, F Acernese, A Agapito +546
From April 10, 2024 to November 18, 2025 Advanced Virgo participated in the fourth observing run of the network of gravitational-wave detectors, together with Advanced LIGO and KAG…
Constraints on primordial black holes from the first part of LIGO-Virgo-KAGRA fourth observing run
M. Andrés-Carcasona, A. J. Iovino, E. Vallejo-Pagès +4
We analyse primordial black hole (PBH) populations using state-of-the-art modelling of PBH binaries, deriving the strongest bounds on PBH abundance in the - rang…
The Instrumented Baffle at the Input Mode Cleaner of Advanced Virgo Plus: Four years of Successful Operation as a Monitor of Stray Light
Dounia Nanadoumgar-Lacroze, Monica Seglar-Arroyo, Mario Martinez +2
The suspended end mirror of the input mode cleaner cavity in the Advanced Virgo Plus interferometer was equipped with an instrumented baffle in spring 2021, serving as a demonstrat…

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…
New modeling of the stray light noise in the main arms of the Einstein Telescope
M. Andrés-Carcasona, J. Grandes Umbert, D. González-Lociga +3
Stray light represents a significant noise source for gravitational wave detectors, requiring an accurate modeling and mitigation to preserve the experiment's sensitivity. In this…
Performance of an instrumented baffle placed at the entrance of Virgo's end mirror vacuum tower during O5
M. Andrés-Carcasona, M. Martínez, Ll. M. Mir +2
In this article, we present results on the simulated performance of an instrumented baffle installed at the entrance of the vacuum towers hosting the end mirrors of Virgo's main Fa…
