Cosmography can be considered as a sort of a model-independent approach to tackle the
dark energy/modified gravity problem. In this review, the success and the shortcomings of …

Cosmography becomes non-predictive when cosmic data span beyond the redshift limit z≃
1. This leads to a strong convergence issue that jeopardizes its viability. In this work, we …

Inflation and dark energy are two of the most relevant aspects of modern cosmology. These
different epochs provide the universe is passing through accelerated phases soon after the …

We examine the observational viability of a class of f (R) gravity cosmological models.
Particular attention is devoted to constraints from the recent observational determination of …

Cosmography is used in cosmological data processing in order to constrain the kinematics
of the universe in a model-independent way, providing an objective means to evaluate the …

In this research paper, we explore a well-motivated parametrization of the time-dependent
deceleration parameter, characterized by a cubic form in cosmic time t, in the context of late …

We extract constraints on the transition redshift z tr, determining the onset of cosmic
acceleration, predicted by an effective cosmographic construction, in the framework of f (T) …

In this paper, we present a cosmological model designed to study the evolution of the
universe based on a new parametrization of the deceleration parameter. The model …

We study the accelerated expansion phase of the universe by using the kinematic approach.
In particular, the deceleration parameter q is parametrized in a model-independent way …

We investigate the entanglement due to geometric corrections in particle creation during
inflation. To do so, we propose a single-field inflationary scenario, nonminimally coupled to …
