Generating gravitational waveform libraries of exotic compact binaries with deep learning
Felipe F. Freitas, Carlos A. R. Herdeiro, António P. Morais +5
Current gravitational wave (GW) detections rely on the existence of libraries of theoretical waveforms. Consequently, finding new physics with GWs requires libraries of non-standar…
Missing large-angle correlations versus even-odd point-parity imbalance in the cosmic microwave background
M. -A. Sanchis-Lozano, F. Melia, M. López-Corredoira +1
Context. The existence of a maximum correlation angle () in the two-point angular temperature correlations of cosmic microwave background (CMB) radiatio…
Ultralight bosonic dark matter in white dwarfs and potential observational consequences
Nicolas Sanchis-Gual, Paula Izquierdo
Fluid and ultralight bosonic dark matter can interact through gravity to form stable fermion-boson stars, which are static and regular mixed solutions of the Einstein-Euler-(comple…
An estimate of the gravitational-wave background from the observed cosmological distribution of quasars
Nicolas Sanchis-Gual, Vicent Quilis, José A. Font
We study the gravitational-wave background from the observed cosmological quasar distribution. Using the DR9Q quasar catalogue from the ninth data release of the Sloan Digital Sky…
A stabilization mechanism for excited fermion-boson stars
Fabrizio Di Giovanni, Saeed Fakhry, Nicolas Sanchis-Gual +2
We study numerically the nonlinear stability of {\it excited} fermion-boson stars in spherical symmetry. Such compound hypothetical stars, composed by fermions and bosons, are grav…
Boson stars in Palatini gravity
Andreu Masó-Ferrando, Nicolas Sanchis-Gual, José A. Font +1
We explore equilibrium solutions of spherically symmetric boson stars in the Palatini formulation of gravity. We account for the modifications introduced in the gr…
