We investigate the growth of matter fluctuations in holographic dark energy cosmologies.
First, we use an overall statistical analysis involving the latest observational data in order to …

We review dark energy models that can present non-negligible fluctuations on scales
smaller than Hubble radius. Both linear and nonlinear evolutions of dark energy fluctuations …

We put constraints on dark energy (DE) properties using PADE parameterization, and
compare it to the same constraints using Chevalier–Polarski–Linder (CPL) and ΛCDM, at …

The rate of structure formation in the Universe is different in homogeneous and clustered
dark energy models. The degree of dark energy clustering depends on the magnitude of its …

In this study, we combine the expansion and the growth data in order to investigate the
ability of the three most popular holographic dark energy models, namely event future …

We study the main cosmological properties of the agegraphic dark energy model at the
expansion and perturbation levels. Initially, using the latest cosmological data, we …

We study the dynamical properties of dark energy based on a large family of Padé
parameterizations for which the dark energy density evolves as the ratio between two …

In this paper, we study the evolution of dark matter perturbations in the linear regime by
considering the possibility of dark energy perturbations. To do this, two popular …

While in the standard cosmological model the accelerated expansion of the Universe is
explained by invoking the presence of the cosmological constant term, it is still unclear the …

Thawing quintessence scalar field models with the various potential forms to explain the late-
time cosmic acceleration are compared to the Λ CDM model in detail by analyzing …
