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…
GRB 241030A: a bright afterglow challenging forward shock emission
J. -G. Ducoin, C. Pellouin, V. Aivazyan +97
Gamma-Ray Burst GRB 241030A (z = 1.411) exhibited a bright afterglow (similar to GRB 221009A), detected across gamma-ray, X-ray, UV, and optical bands, providing a probe of GRB aft…
Blazars as a Potential Origin of the KM3-230213A Event
The KM3NeT Collaboration
The KM3NeT collaboration has reported the detection of the highest energy neutrino event observed to date. The energy of the event is of the order of 220 PeV hinting towards a neut…
From the Virgo interferometer calibration to the bias and uncertainty of the h(t) detector strain during the O4 run
Cervane Grimaud, Florian Aubin, Benoît Mours +6
Since the first gravitational wave detection in 2015, ground-based interferometer sensitivities have significantly improved, requiring highly precise calibration to ensure accurate…
Characterizing Candidate Blazar Counterparts of the Ultra-High-Energy Event KM3-230213A
KM3NeT Collaboration, MessMapp Group, LAT Collaboration +13
High-energy astrophysical neutrinos serve as crucial messengers for understanding hadronic acceleration processes and identifying the origins of cosmic rays, with blazars among the…
The Virgo Newtonian calibration system for the O4 observing run
Florian Aubin, Eddy Dangelser, Dimitri Estevez +5
After initial tests performed during previous observing runs, a Newtonian Calibrator (NCal) system was developed and installed on the Virgo gravitational wave detector for the O4 o…
