Hubble Tension as a Window on the Gravitation of the Dark Matter Sector

Open access

Abstract

A simple and minimal extension of the standard cosmological ΛCDM model in which dark matter experiences an additional long-range scalar interaction is demonstrated to alleviate the long-lasting Hubble tension while primordial nucleosynthesis predictions remain unaffected and passing by construction all current local tests of general relativity. The theoretical formulation of this ΛβCDM model and its comparison to astrophysical observations are presented to prove its ability to fit existing data and potentially resolve the tension.

  • From a theoretical perspective, this opens the question of whether one can modify the dark matter gravity sector independently of the standard matter sector, in particular since such models have become candidates to a solution of the Hubble tension.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
