Study of the cosmological tensions and DESI-DR2 in the framework of the Little Rip model

Safae Dahmani, Imad El Bojaddaini, Amine Bouali +2

We present an analysis that investigates the $H_{0}$ and $S_{8}$ tensions by considering a dark energy model. The latter is a late-time model characterized by a future abrupt event kno…

Emergence of running vacuum energy in $f (R, T)$ gravity : Observational constraints

Ahmed Errahmani, Mounia Magrach, Safae Dahmani +2

In this work, we present a new analysis for $f (R, T)$ gravity by exploring the energy momentum tensor. We demonstrate that $f (R, T)$ gravity with the form $f (R, T) = R + 2 I^º^{2} I^» T - 2 I^$ i…

Constraints on Power Law and Exponential models in $f (Q)$ 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…
