Cosmological test of a length-preserving biconnection gravity
Dalale Mhamdi, Amine Bouali, Taoufik Ouali +1
We investigate the cosmological implications of an extended gravitational framework based on biconnection gravity, constructed from the Schrdinger connection and its dual…

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…
