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 $\chi^2$ tests considering fixed values of $H_0$ and $V_G$, 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 $H_0$ and $V_G$, being the BAO data set the most powerful tool to test MOG predictions, due to its constraining power.

使用 Ia 型超新星、宇宙天文钟和重子声学振荡测试修正引力理论 (MOG)

我们在宇宙学背景下分析了 Moffat 提出的 MOdified Gravity (MOG) 理论。我们使用来自 Ia 型超新星 (SNe Ia)、重子声波振荡 (BAO) 和宇宙天文台 (CC) 的数据来测试 MOG 预测。为此,我们执行 $\chi^2$ 测试,考虑 $H_0$ 和 $V_G$ 的固定值,即理论中标量场之一的自相互作用势。我们的结果表明,MOG 理论与 $H_0$ 和 $V_G$ 的某些特定值的所有数据集一致,由于其约束能力,BAO 数据集是测试 MOG 预测的最强大工具。
