Testing Gravity with Logarithmic Equation of State Using Latest Cosmological Data
Chaymae Karam, Dalale Mhamdi, Taoufik Ouali +2
In this paper, we investigate the late-time accelerated expansion of the Universe in power law gravity, where a logarithmic dark energy parametrization is considered: $ω_{de…
Testing Gauss-Bonnet Gravity with DESI BAO Data
Praveen Kumar Dhankar, Dalale Mhamdi, Albert Munyeshyaka +3
In the present paper, we observationally constrain f (G) gravity at the background level using Type Ia supernovae from the Pantheon Plus (PP) sample, cosmic chronometer (CC) data,…
Constraints on Power Law and Exponential models in Gravity
Dalale Mhamdi, Farida Bargach, Safae Dahmani +2
In this paper, we observationally test the \( f(Q) \) gravity model at both background and perturbation levels using Pantheon, Hubble measurements, and Redshift Space Distortio…
Observational constraints on the growth index parameters in gravity
Dalale Mhamdi, Safae Dahmani, Amine Bouali +2
In this study, we analyse constraints on the growth index of matter perturbations, , within the framework of gravity, using recent cosmological observations, at the backg…
Diagnostic Approaches for Interacting generalized holographic Ricci Dark Energy Models
Omar Enkhili, Farida Bargach, Dalale Mhamdi +2
In this paper, we present an analytical solution for the interacting generalized holographic dark energy model, assuming a linear interaction rate between dark energy and dark matt…
Cosmological constraints on dynamical dark energy model in gravity
Omar Enkhili, Safae Dahmani, Dalale Mhamdi +2
Extended teleparallel gravity, characterized by function where is the non-metricity scalar, is one of the most promising approaches to general relativity. In this paper,…
