摘要:
We investigate the possibility of a Bianchi V universe in the modified gravitational field theory of f(R,T). We have considered a Lagrangian model in connection between the trace of the energy-momentum tensor T and the Ricci scalar R . In order to solve the field equations a power law for the scaling factor was also considered. To make a comparison of the model parameters with the observational data we put constraint on the model under the datasets of the Hubble parameter, Baryon Acoustic Oscillations, Pantheon, joint datasets of Hubble parameter + Pantheon and collective datasets of the Hubble parameter + Baryon Acoustic Oscillations + Pantheon. The outcomes for the Hubble parameter in the present epoch are reasonably acceptable, especially our estimation of this H0 is remarkably consistent with various recent Planck Collaboration studies that utilize the Lambda-CDM model.
