EPJ Plus Focus Point on Tensions in Cosmology from Early to Late Universe: The Value of the Hubble Constant and the Question of Dark Energy
- Published on 03 March 2023
Guest editors: S. Capozziello, V.G. Gurzadyan
The papers included in this Focus Point collection are devoted to one of the hot topics in modern cosmology - the Hubble constant tension – claimed as a discrepancy between the descriptions of the early and late Universe. A broad range of topics are involved in the Hubble tension issue, from the sophisticated methods of observational data analysis up to dark energy models dealing with modifications of the standard cosmological model and related to the extensions of the General Relativity. The papers included in the collection are authored by known experts and groups, and reflect the diversity of approaches, both, aiming in solving the tension improving measurements and datasets and in searching for new physics capable of addressing the problem.
