Neutrino mass tension or suppressed growth rate of matter perturbations?
William Giarè, Olga Mena, Enrico Specogna +1
Assuming a minimal CDM cosmology with three massive neutrinos, the joint analysis of Planck cosmic microwave background data, DESI baryon acoustic oscillations, and distance mod…
Sign Switching in Dark Sector Coupling Interactions as a Candidate for Resolving Cosmological Tensions
Miguel A. Sabogal, Emanuelly Silva, Rafael C. Nunes +2
The CDM model has successfully explained a wide range of cosmological observations, but is increasingly challenged by the emergence of cosmological tensions, particularly the Hu…
Planck-PR4 anisotropy spectra show (better) consistency with General Relativity
Enrico Specogna, William Giarè, Eleonora Di Valentino
We present the results from a series of analyses on two parametric tests of gravity that modify the growth of linear, sub-horizon matter perturbations in the CDM model. The firs…
Dark sector interaction and the supernova absolute magnitude tension
Rafael C. Nunes, Eleonora Di Valentino
It has been intensively discussed if modifications in the dynamics of the Universe at late times is able or not to solve the tension. On the other hand, it has also been argu…
The unfinished fabric of the three neutrino paradigm
Francesco Capozzi, Eleonora Di Valentino, Eligio Lisi +3
In the current 3nu paradigm, flavor oscillations probe 3 mixing angles (theta_12, theta_23, theta_13), one CP phase delta, and two squared mass differences delta m^2>0 and Delta m^…
Generalized Emergent Dark Energy Model and the Hubble Constant Tension
Weiqiang Yang, Eleonora Di Valentino, Supriya Pan +2
We investigate a generalized form of the phenomenologically emergent dark energy model, known as generalized emergent dark energy (GEDE), introduced by Li and Shafieloo [Astrophys.…
In the Realm of the Hubble tension a Review of Solutions
Eleonora Di Valentino, Olga Mena, Supriya Pan +6
The CDM model provides a good fit to a large span of cosmological data but harbors areas of phenomenology. With the improvement of the number and the accuracy of observations, d…
Dynamical Dark sectors and Neutrino masses and abundances
Weiqiang Yang, Eleonora Di Valentino, Olga Mena +1
We investigate generalized interacting dark matter-dark energy scenarios with a time-dependent coupling parameter, allowing also for freedom in the neutrino sector. The models are…
All-inclusive interacting dark sector cosmologies
Weiqiang Yang, Eleonora Di Valentino, Olga Mena +2
In this paper we explore possible extensions of Interacting Dark Energy cosmologies, where Dark Energy and Dark Matter interact non-gravitationally with one another. In particular,…
Metastable dark energy models in light of Planck 2018: Alleviating the tension
Weiqiang Yang, Eleonora Di Valentino, Supriya Pan +2
We investigate the recently introduced metastable dark energy (DE) models after the final Planck 2018 legacy release. The essence of the present work is to analyze their evolution…
Non-minimal dark sector physics and cosmological tensions
Eleonora Di Valentino, Alessandro Melchiorri, Olga Mena +1
We explore whether non-standard dark sector physics might be required to solve the existing cosmological tensions. The properties we consider in combination are an interaction betw…
Interacting scenarios with dynamical dark energy: observational constraints and alleviation of the tension
Supriya Pan, Weiqiang Yang, Eleonora Di Valentino +2
We investigate interacting scenarios which belong to a wider class, since they include a dynamical dark energy component whose equation of state follows various one-parameter param…
Interacting dark energy with time varying equation of state and the tension
Weiqiang Yang, Ankan Mukherjee, Eleonora Di Valentino +1
Almost in all interacting dark energy models present in the literature, the stability of the model becomes potentially sensitive to the dark energy equation of state parameter $w_x…
