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…
