RSD constraints on power-law gravity using Barboza-Alcaniz and Jassal-Bagla-Padmanabhan parametrizations
Chaymae karam, Dalale Mhamdi, Taoufik Ouali +2
We investigate the late-time accelerated expansion of the Universe in power-law gravity, , combined with two dynamical dark…

Testing the bulk viscosity within the f(R,T) gravity in light of DESI-DR2 observations
Omayma Saddiki, Safae Dahmani, Taoufik Ouali +1
We investigate the cosmological implications of the bulk viscosity within the framework of gravity by considering the linear model , where characterizes…

Testing the running vacuum model in light of DESI-DR2 Measurements
Lamiae Kardaddech, Safae Dahmani, Amine Bouali +2
Motivated by the fact that quantum effects leave an imprint on the vacuum equation of state, making it depart from the standard cosmological constant relation, $P_{\rm vac}=-ρ_{\rm…
