Observational constraints on the unified dark matter and dark energy model based on the quark bag model
Ariadna Montiel, Vincenzo Salzano, Ruth Lazkoz
In this work we investigate if a small fraction of quarks and gluons, which escaped hadronization and survived as a uniformly spread perfect fluid, can play the role of both dark m…
Parameter estimation of a nonlinear magnetic universe from observations
Ariadna Montiel, Nora Bretón, Vincenzo Salzano
The cosmological model consisting of a nonlinear magnetic field obeying the Lagrangian L= γF^α, F being the electromagnetic invariant, coupled to a Robertson-Walker geometry is tes…
Nonparametric reconstruction of the cosmic expansion with local regression smoothing and simulation extrapolation
Ariadna Montiel, Ruth Lazkoz, Irene Sendra +2
In this work we present a nonparametric approach, which works on minimal assumptions, to reconstruct the cosmic expansion of the Universe. We propose to combine a locally weighted…
