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 …

In this review we consider in detail different theoretical topics associated with interaction in
the dark sector. We study linear and nonlinear interactions which depend on the dark matter …

We consider gravity mediated by non-metricity, with vanishing curvature and torsion. The
gravitational action, including an arbitrary function of the non-metric scalar, is investigated in …

Over the last years some interest has been gathered by f (Q) theories, which are new
candidates to replace Einstein's prescription for gravity. The nonmetricity tensor Q allows to …

In the current paper, a dark energy (DE) model reconstructed from the well‐motivated
deceleration parameter (DP) q (z)= q 0+ q 1 z/(1+ z) 2 q(z)=q_0+q_1z/(1+z)^2 is analyzed. A …

Measurements of the H 0 and σ 8 parameters within the standard cosmological model
recently highlighted significant statistical tensions between the cosmic microwave …

In this work, we explore how modified gravity theories based on the nonmetricity scalar,
known as f (Q) gravity, affect the propagation of gravitational waves from inspiraling of binary …

The aim of this paper is to introduce a new modified gravity theory named f (G, T) f (G, T)
gravity (GG and T are the Gauss–Bonnet invariant and trace of the energy-momentum …

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 …

We propose a new parametrization of dark energy motivated by thermodynamics. To this
aim, we consider Padé polynomials to reconstruct the form of deceleration parameter …
