Résumé |
Since its appearance almost a decade ago, the Hubble Tension received a great deal
of proposals to solve it, with none being completely successful. However, new
state of the art data improve our assessment of these models and better constrain
their parameters.
In this talk, which is based on the work in arXiv: 2312.09814, an evaluation of
eleven cosmological models is presented. These models consist of five classical
extensions of ΛCDM, Early Dark Energy, the Majoron and the varying electron mass
models, along with three of the latter’s extensions. This evaluation, previously
performed using Planck, ACT and SDSS data (up to DR-12), is now updated with
recent SPT-3G, SDSS-DR16 and SH0ES data.
Using a set of novel tension metrics, these models are ranked based on which one
is able to reduce the tension, and which requires further study before potentially
becoming the new concordance model of Cosmology. |
