In this work, we study different types of dark energy (DE) models in the framework of the
cosmographic approach, with emphasis on the running vacuum models (RVMs). We assess …

Using mock data for the Hubble diagrams of type Ia supernovae (SNIa) and quasars (QSOs)
generated based on the standard model of cosmology, and using the least-squares method …

The cosmographic approach, a Taylor expansion of the Hubble function, has been used as
a model-independent method to investigate the evolution of the universe in the presence of …

In the context of a cosmography approach to using the data of the Hubble diagram for
supernovae, quasars, and gamma-ray bursts, we study dark energy (DE) parameterizations …

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 …

This study investigates accelerated cosmic expansion using the Viscous Modified Chaplygin
Gas (VMMG) and Generalized Cosmic Chaplygin Gas (GCCM) within Horava–Lifshitz …

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 …

In this work we examine the recently proposed phenomenological emergent dark energy
(PEDE) model by 1, using the latest observational data in both expansion and perturbation …

There are several methods for model selection in cosmology which have at least two major
goals, that of finding the correct model or predicting well. In this work, we discuss through a …

We perform a comparative study of different types of dynamical dark energy models (DDEs)
using the cosmographic method. Among the models being examined herein we have the …
