Description
In this talk, we will review some phenomenological diffusion models within the gravitational framework of Unimodular Gravity. We will show that, when regarding non-gravitational interactions between cold dark matter and an effective cosmological constant, it is possible to address one of the modern cosmological problems: the discrepancy between the early and late time inferred value of the current Hubble parameter, H0. Finally, we will impose some constraints on the main diffusion parameters to study the viability of these models.
