Abstract

We analyse the MOdified Gravity (MOG) theory, proposed by Moffat, in a cosmological context. We use data from Type Ia Supernovae (SNe Ia), Baryon Acoustic Oscillations (BAO) and Cosmic Chronometers (CC) to test MOG predictions. For this, we perform χ2\chi^2 tests considering fixed values of H0H_0 and VGV_G, the self-interaction potential of one of the scalar fields in the theory. Our results show that the MOG theory is in agreement with all data sets for some particular values of H0H_0 and VGV_G, being the BAO data set the most powerful tool to test MOG predictions, due to its constraining power.
