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…
QTAM: QTransform Amplitude Modulation
Lorenzo Asprea, Francesco Sarandrea, Alessio Romano +3
We present Q-Transform Amplitude Modulation (QTAM), a novel, fully invertible implementation of the Constant-Q Transform algorithm, designed to enable robust signal denoising and t…
Misinterpreting spin precession as orbital eccentricity in gravitational-wave signals
Snehal Tibrewal, Aaron Zimmerman, Jacob Lange +1
The increasing scope and breadth of gravitational wave detectors is providing the opportunity to explore new parameters in gravitational-wave astronomy. Eccentricity and spin-prece…
A parametrized model for gravitational waves from eccentric, precessing binary black holes: theory-agnostic tests of General Relativity with pTEOBResumS
Danilo Chiaramello, Nicolò Cibrario, Jacob Lange +4
Gravitational waves from binary black hole (BBH) mergers allow us to test general relativity in the strong-field, high-curvature regime. However, existing gravitational wave-based…
Revisiting GW150914 with a non-planar, eccentric waveform model
Rossella Gamba, Jacob Lange, Danilo Chiaramello +2
The first direct detection of gravitational waves by the LIGO collaboration, GW150914, marked the start of a new exciting era in astronomy, enabling the study of the Universe throu…
