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…
On the Metric gravity Viability in Accounting for the Binned Supernovae Data
A. Valletta, G. Montani, M. G. Dainotti +1
In this work, two models of metric gravity in the Jordan frame are investigated as a dynamical description of the late-time cosmic expansion using binned Type Ia Supernovae…
Creation of Viscous Dark Energy by the Hubble Flow: Comparison with SNe Ia Master Sample Binned Data
Iolanda Navone, Maria Giovanna Dainotti, Elisa Fazzari +3
We study a family of cosmological models featuring dynamical dark energy (DE), based on the idea that the creation of its constituents arises from the gravitational field of the ex…
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…
Investigating -Inflation: background evolution and constraints
Elisa Fazzari, Chiara De Leo, Giovanni Montani +3
In this work, we investigate the possibility of generating an inflationary mechanism within the framework of a metric- modified gravity theory, formulated in the Jordan frame…
Decay of dark energy into dark matter in a metric gravity: effective running Hubble constant
Giovanni Montani, Mariaveronica De Angelis, Maria Giovanna Dainotti
We examine a modified late-Universe dynamics where dark energy decays into dark matter, within the framework of metric -gravity in the Jordan frame. After a detailed analysis…
