As the 2015 results of Plancks mission have recently been made available, it is interesting to check the evolution of the scale factor and of the Hubble parameter in the light of these results. Two models in line with Einsteins field equations and with the hot big bang scenario for a flat Universe are used to allow a comparison : (1) the classical one using density parameters for matter content (baryonic and dark matter) and dark energy ; (2) an alternative model, already used in the past, and assuming the Hubble parameter to contain a term constant in time. Both models are coherent with each other except for some discrepancy about the density, which can be ascribed to the different hypotheses made. This opens a way for further interpretation of the origin of dark energy.

Varying Gravity from a Modified Fractional Model: Observational Constraints and Slow-Fast Dynamics
A fractional gravity model with dynamical G and scalar field fits late-time data only in the μ=0 case, mimics ΛCDM expansion, but is disfavored by BIC and yields an unphysically large universe age.

Observationally Constrained Cosmological model in $f(Q,\mathcal{L}_{m})$ Gravity with $H(z)$ parameterization
An f(Q, L_m) gravity model with a parameterized H(z) fits observational data, yielding a transition redshift z_t ≈ 0.643 and cosmic age 13.724 Gyr, consistent with ΛCDM.
