Simflowny 3: An upgraded platform for scientific modelling and simulation
C. Palenzuela, B. Miñano, A. Arbona +3
Simflowny is an open platform which automatically generates efficient parallel code of scientific dynamical models for different simulation frameworks. Here we present major upgrad…
The horizon problem as a clue: a smooth big bang?
Carles Bona
The necessary and sufficient condition for the absence of particle horizons in a big bang Friedmann-Robertson-Walker universe is provided. It happens to be a "smooth big bang" init…
Kaluza-Klein Cosmology: the bulk metric
Carles Bona, Miguel Bezares
The Cosmological Principle is applied to a five-dimensional vacuum manifold. The general (non-trivial) solution is explicitly given. The result is a unique metric, parametrized wit…
A Simflowny-based high-performance 3D code for the generalized induction equation
Daniele Viganò, David Martínez-Gómez, José A. Pons +6
In the interior of neutron stars, the induction equation regulates the long-term evolution of the magnetic fields by means of resistivity, Hall dynamics and ambipolar diffusion. De…
3+2 Cosmology: unifying FRW metrics in the bulk
Carles Bona, Miguel Bezares, Bartolomé Pons-Rullan +1
The Cosmological Problem is considered in a five-dimensional (bulk) manifold with two time coordinates, obeying vacuum Einstein field equations. The evolution formalism is used the…
A Simflowny-based finite-difference code for high-performance computing in Relativity
Carlos Palenzuela, Borja Miñano, Daniele Viganò +6
The tremendous challenge of comparing our theoretical models with the gravitational-wave observations in the new era of multimessenger astronomy requires accurate and fast numerica…
