Parametric and nonparametric methods hint dark energy evolution
  We study dark energy through the viewpoints of parametric and nonparametric
analyses of late-time cosmological data. We consider four Hubble parameter
priors reflecting the Hubble tension and make use of two phenomenological
functions, namely, a normalized dark energy density and a compactified dark
energy equation of state. We predict the shape of both functions and present
new constraints on the dark energy equation of state. The results hint at dark
energy evolution regardless of the choice of the method and of the priors. The
fact that similar evolutions for the dark energy densities are found through
drastically different approaches suggests that the features found in this paper
are driven by the data, and are not artifact of the reconstruction methods
applied.
