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…

Proto-neutron star oscillations including accretion flows

Dimitra Tseneklidou, Raimon Luna, Pablo Cerdá-Durán +1

The gravitational wave signature from core-collapse supernovae (CCSNe) is dominated by quadrupolar oscillation modes of the newly born proto-neutron star (PNS), and could be detect…

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…
