Analyzing the H0 tension in F(R) gravity models

The Hubble constant tension problem is analyzed in the framework of a class of modified gravity, the so-called F(R) gravity. To do so, we explore two models: an exponential and a power-law F(R) gravities, which includes an early dark energy (EDE) term in the latter. These models can describe both an...
