Running Hubble Constant with the Redshift as a Marker of Evolutionary Dark Energy

Nakia Carlevaro, Giovanni Montani, Maria Giovanna Dainotti

We discuss the interpretation of an observed running Hubble constant with the redshift, in terms of the possible underlying physical scenario. Assuming, like in the CDM model, t…

Modifying CDM dynamics via out-of-equilibrium axions: reconciling SH0ES and DESI values

Giovanni Montani, Luis A. Escamilla, Nakia Carlevaro +1

We investigate late-Universe dynamics in which the dark matter component is described by axion particles. The proposed framework departs from the standard CDM paradigm due to a…

QCD CP-violation scenario for a revised cosmological dynamics: analysis of the binned Pantheon Sample of Super Novae Ia

Giovanni Montani, Nakia Carlevaro, Maria Giovanna Dainotti +1

We investigate a modified cosmological dynamics in which the Universe is composed of baryonic matter and a complex (classical) scalar field. The phase component of this field is id…

Reproducing anomalous transport coefficients from electro-static tokamak edge turbulent dynamics

Fabio Moretti, Francesco Cianfrani, Nakia Carlevaro +1

Turbulent transport near the X-point of a large tokamak is examined using local, gradient-driven simulations that determine the saturated plasma profiles. The distribution of a rep…

Decay of quintessence into dark matter: mitigating the Hubble tension?

Giovanni Montani, Luis A. Escamilla, Nakia Carlevaro +1

We propose a revised cosmological scenario that extends the Cold Dark Matter (CDM) framework by incorporating metric gravity in the Jordan frame. In this model, the d…

Two Dynamical Scenarios for Binned Master Sample Interpretation

Giovanni Montani, Elisa Fazzari, Nakia Carlevaro +1

We analyze two different scenarios for the late Universe dynamics, resulting into Hubble parameters deviating from the CDM, mainly for the presence of an additional free paramet…
