We investigate the H0 tension in a range of extended model frameworks beyond the standard ΛCDM without the data from the cosmic microwave background (CMB). Specifically, we adopt the data from baryon acoustic oscillations, big bang nucleosynthesis, and type Ia supernovae as indirect measurements of H0 to study the tension. We show that the estimated value of H0 from indirect measurements is overall lower than that from direct local ones regardless of the data sets and a range of extended models to be analyzed, which indicates that, although the significance of the tension varies depending on models, the H0 tension persists in a broad framework beyond the standard ΛCDM model even without CMB data. ar X iv :2 10 5. 12 31 2v 2 [ as tr oph .C O ] 2 A ug 2 02 1
