Running Hubble constant: evolutionary Dark Energy
Giovanni Montani, Nakia Carlevaro, Maria G. Dainotti
We discuss an evolutionary dark energy model, based on the presence of non-equilibrium effects on the dark energy constituents, which are described via a bulk viscosity contributio…
Modified gravity in the presence of matter creation: scenario for the late Universe
Giovanni Montani, Nakia Carlevaro, Mariaveronica De Angelis
We consider a dynamic scenario for characterizing the late Universe evolution, aiming to mitigate the Hubble tension. Specifically, we consider a metric gravity in the Jorda…
Kinetic Model for Dark Energy - Dark Matter Interaction: Scenario for the Hubble Tension
Giovanni Montani, Nakia Carlevaro, Luis A. Escamilla +1
We analyze a model for Dark Energy - Dark Matter interaction, based on a decaying process of the former into the latter. The dynamical equations are constructed following a kinetic…
Slow-rolling scalar dynamics and as solution for the Hubble tension
Giovanni Montani, Nakia Carlevaro, Maria G. Dainotti
We construct a theoretical framework to interpret the Hubble tension by means of a slow-rolling dynamics of a self-interacting scalar field. In particular, we split the Friedmann e…
Metric gravity with dynamical dark energy as a scenario for the Hubble tension
Giovanni Montani, Mariaveronica De Angelis, Flavio Bombacigno +1
We introduce a theoretical framework to interpret the Hubble tension, based on the combination of a metric gravity with a dynamical dark energy contribution. The modified gr…
Perspectives in Cosmology, Gravitation and Multidimensions
Giovanni Montani, Nakia Carlevaro, Francesco Cianfrani +1
Recent developments from the activity of the CGM Group are discussed. Cosmological implications of fundamental approaches to quantization of gravity are presented in order to fix t…
