Snowmass2021 - Letter of interest cosmology intertwined II: The hubble constant tension

Eleonora Di Valentino, +94 more
TL;DR: In this article, the authors focus on the 4.4σ tension between the Planck estimate of the Hubble constant H0 and the SH0ES collaboration measurements and discuss how the next decade's experiments will be crucial.
Journal ArticleDOI

Cosmology intertwined III: fσ8 and S8

Eleonora Di Valentino, +92 more
TL;DR: In this article, the authors focus on the tension between Planck data and weak lensing measurements and redshift surveys, and discuss the importance of trying to fit multiple cosmological datasets with complete physical models, rather than fitting individual datasets with a few handpicked theoretical parameters.
Journal ArticleDOI

The H 0 tension in light of vacuum dynamics in the universe

TL;DR: In this article, the authors investigated the impact of the running vacuum model (RVM) and related models on the controversy of the precise value of H 0, which is the first ever parameter of modern cosmology and one of the prime parameters in the field, still goes on and on after over half a century of measurements.
Journal ArticleDOI

First Evidence of Running Cosmic Vacuum: Challenging the Concordance Model

TL;DR: In this article, a running vacuum model (RVMs) with dynamical vacuum energy density was proposed and compared to the traditional concordance ΛCDM model at an unprecedented level of 4.2σ.
Journal ArticleDOI

First evidence of running cosmic vacuum: challenging the concordance model

TL;DR: In this paper, a running vacuum model (RVM) is proposed, in which a nonvanishing constant term and a series of powers of the Hubble rate are used to describe the dynamics of the universe.
