Boson Star Factory: Past, Present, and Future
Romain Gervalle, Jorge Filipe Mónico Delgado, Etevaldo dos Santos Costa Filho +4
Boson stars are self-gravitating solitons of the Einstein-Klein-Gordon equations for a massive complex scalar field, and arguably the simplest horizonless compact objects arising i…
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…
Quasinormal Modes in Modified Gravity using Physics-Informed Neural Networks
Raimon Luna, Daniela D. Doneva, José A. Font +2
In this paper, we apply a novel approach based on physics-informed neural networks to the computation of quasinormal modes of black hole solutions in modified gravity. In particula…
Numerical relativity surrogate models for exotic compact objects: the case of head-on mergers of equal-mass Proca stars
Raimon Luna, Miquel Llorens-Monteagudo, Ana Lorenzo-Medina +6
We present several high-accuracy surrogate models for gravitational-wave signals from equal-mass head-on mergers of Proca stars, computed through the Newman-Penrose scalar . W…
