In this work, we consider F(R) alternative theories of gravity with an eye to Noether symmetry through the gauge theorem. For non-vacuum models, one finds {\Lambda} like gravity with energy density of Chaplygin Gas. We also obtain the effective equation of state parameter for corresponding cosmology and scale factor behavior with respect to cosmic time which show that the model provides viable EoS and scale factor with respect to observational data.

Dark Matter and Energy-Momentum Squared Gravity
Energy-momentum squared gravity can reproduce flat galactic rotation curves only because its free parameter s is set from the observed velocities.
