We review the paradigm of holographic dark energy (HDE), which arises from a theoretical
attempt of applying the holographic principle (HP) to the dark energy (DE) problem. Making …

We construct an updated extended compilation of distinct (but possibly correlated) f σ 8 (z)
redshift space distortion (RSD) data published between 2006 and 2018. It consists of 63 …

We apply the holographic principle in the cosmological context through the nonadditive
Tsallis entropy used to describe the thermodynamic properties of nonstandard statistical …

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 …

A novel fractal structure for the cosmological horizon, inspired by COVID-19 geometry, which
results in a modified area entropy, is applied to cosmology in order to serve dark energy …

In this work, we examine the possibility that the dark energy (DE) density, ρ de, can be
dynamical and appear as a power series expansion of the Hubble rate (and its time …

We investigate the bounce realization arising from the application of the holographic
principle in the early universe, inspired by its well-studied late-time application. We first …

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 …

We investigate the Tsallis holographic dark energy (THDE) models in the context of
perturbations' growth. We assume the description of dark energy by considering the …

In this paper we present conjoined constraints on several cosmological models from the
expansion history H (z) and cosmic growth f σ 8. The models we study include the CPL w 0 …
