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 $f(R,T)$ gravity by considering the linear model $f(R,T)=R+2\lambda T$, where $\lambda$ characterizes…
