Abstract |
We introduce a theoretical framework to interpret the Hubble tension, based on the combination of a metric f(R) gravity with a dynamical dark energy contribution. The modified gravity provides the non-minimally coupled scalar field responsible for the proper scaling of the Hubble constant, in order to accommodate for the local SNIa pantheon+ data and Planck measurements. The dynamical dark energy source, which exhibits a phantom divide line separating the low redshift quintessence regime (-1 < w < -1/3) from the phantom contribution ( w < -1) in the early Universe, guarantees the absence of tachyonic instabilities at low redshift. The resulting H-0(z) profile rapidly approaches the Planck value, with a plateau behaviour for z greater than or similar to 5. In this scenario, the Hubble tension emerges as a low redshift effect, which can be in principle tested by comparing SNIa predictions with far sources, like QUASARS and gamma ray bursts. |
