Abstract:
In this work we investigate the properties of the accelerated expansion in a theoretical model which extends the fundamental Einstein-Hilbert action by considering geometrical effects from the Gauss-Bonnet invariant (G) and the square of the energy-momentum tensor (T). We investigate the physical properties by considering the linear stability theory, analyzing the phase space structure and the dynamical consequences. Lastly, we obtain various observational constraints for different parameters associated to this model, discussing the viability of the present cosmological scenario.
