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…
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…
Numerical simulations of oscillating and differentially rotating neutron stars
Santiago Jaraba, Jérôme Novak, Micaela Oertel
The remnants of binary neutron star mergers are expected to be massive, rapidly rotating stars whose oscillations produce gravitational waves in the kilohertz band. The degree of d…
Effects of dynamical capture on two equal-mass nonspinning black holes
Jorge L. Rodríguez-Monteverde, Santiago Jaraba, Juan García-Bellido
Dynamical captures of black holes are unique events that provide an exceptional opportunity to probe the strong-field regime of gravitational physics. In this article, we perform n…
First astrometric constraints on parity-violation in the gravitational wave background
Santiago Jaraba, Sachiko Kuroyanagi, Qiuyue Liang +2
Astrometry, the precise measurement of stellar positions and velocities, offers a promising approach to probing the low-frequency stochastic gravitational wave background (SGWB). N…
Astrometric constraints on stochastic gravitational wave background with neural networks
Marienza Caldarola, Gonzalo Morrás, Santiago Jaraba +3
Astrometric measurements provide a unique avenue for constraining the stochastic gravitational wave background (SGWB). In this work, we investigate the application of two neural ne…
Spin induction from scattering of two spinning black holes in dense clusters
Jorge L. Rodríguez-Monteverde, Santiago Jaraba, Juan García-Bellido
In this paper, we use numerical relativity to study the spin induction effect within close hyperbolic encounters of initially spinning black holes. We review the initially non-spin…
A numerical-relativity surrogate model for hyperbolic encounters of black holes: challenges in parameter estimation
Joan Fontbuté, Tomas Andrade, Raimon Luna +5
We present a surrogate numerical-relativity model for close hyperbolic black-hole encounters with equal masses and spins aligned with the orbital momentum. Our model, generated in…
Stochastic gravitational wave background constraints from Gaia DR3 astrometry
Santiago Jaraba, Juan García-Bellido, Sachiko Kuroyanagi +2
Astrometric surveys can be used to constrain the stochastic gravitational wave background (SGWB) at very low frequencies. We use proper motion data provided by Gaia DR3 to fit a ge…
Bayesian parameter estimation for targeted anisotropic gravitational-wave background
Leo Tsukada, Santiago Jaraba, Deepali Agarwal +1
Extended sources of the stochastic gravitational backgrounds have been conventionally searched on the spherical harmonics bases. The analysis during the previous observing runs by…
The stochastic gravitational wave background from close hyperbolic encounters of primordial black holes in dense clusters
Juan García-Bellido, Santiago Jaraba, Sachiko Kuroyanagi
The inner part of dense clusters of primordial black holes is an active environment where multiple scattering processes take place. Some of them give rise from time to time to boun…
Black hole induced spins from hyperbolic encounters in dense clusters
Santiago Jaraba, Juan Garcia-Bellido
The black holes that have been detected via gravitational waves (GW) can have either astrophysical or primordial origin. Some GW events show significant spin for one of the compone…
