Observational constraints on f(R, T) gravity with $$f(R,T) = R + h(T)$$

Abstract The present cosmological model deals with modified f ( R , T ) gravity theory $$f(R,T)=R+h(T)$$ f ( R , T ) = + h in the background of homogeneous and isotropic FLRW space-time model. Four choices h have been studied examined from two observational data sets. It is found that III, namely, linear combination power law logarithmic form more consistent observed than others. However, all four considered models are a worse fit LCDM
