Horizon absorption in eccentric precessing binary black hole inspirals and its importance for gravitational wave data analysis
Alberto Álvaro-Díaz, Gonzalo Morras
During the evolution of a binary black hole, energy and angular momentum are exchanged between the orbital motion and the individual black holes through horizon absorption, modifyi…

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…

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…
