Nonparametric Reconstruction of the Om Diagnostic to Test ΛCDM

Nonparametric Reconstruction of the Om Diagnostic to Test ΛCDM

In this work, we consider an Om diagnostic using a non-parametric reconstruction by employing the Loess–Simex factory. This procedure allows us to perform a model-independent comparison for w(z) with the astrophysical data. The concordance model can be tested with the advantage that our approach rep...
