Towards solving General Relativity with Physics-Informed Neural Networks
Juan A. Carretero, Jorge F. Urbán, Fernando Abalos +4
Physics-Informed Neural Networks (PINNs) are a machine-learning framework for approximating solutions to systems of partial differential equations by constraining neural networks t…
Numerical simulations of divergence-type theories for conformal dissipative fluids
Pablo Montes, Marcelo E. Rubio, Oscar A. Reula
We present the first numerical simulations of the symmetric--hyperbolic theory for conformal dissipative relativistic fluids developed in [1]. In this theory, the information of th…
Relativistic force-free models of the thermal X-ray emission in millisecond pulsars observed by NICER
Federico Carrasco, Joaquin Pelle, Oscar Reula +2
Several important properties of rotation-powered millisecond pulsars (MSPs), such as their mass-radius ratio, equation of state and magnetic field topology, can be inferred from pr…
Skylight: a new code for general-relativistic ray-tracing and radiative transfer in arbitrary spacetimes
Joaquín Pelle, Oscar Reula, Federico Carrasco +1
To reproduce the observed spectra and light curves originated in the neighborhood of compact objects requires accurate relativistic ray-tracing codes. In this work, we present Skyl…
Magnetospheres of black hole-neutron star binaries
Federico Carrasco, Masaru Shibata, Oscar Reula
We perform force-free simulations for a neutron star orbiting a black hole, aiming at clarifying the main magnetosphere properties of such binaries towards their innermost stable c…
New Numerical Interface Scheme for the Kurganov-Tadmor second-order Method
Pablo Montes, Oscar Reula
In this paper, we develop a numerical scheme to handle interfaces across computational domains in multi-block schemes for the approximation of systems of conservation laws. We are…
