TEIXEIRA Elsa (University of Sheffield)
Illuminating Observational Tensions in a Coupled Dark Sector

(LUPM/Particules, Astroparticules, Cosmologie : Théorie)


Reconciling the standard model's theoretical predictions with precision measurements from multiple probes stands as one of the most pressing challenges of modern cosmology. During the last decade, increasing evidence for persistent discrepancies in the value of cosmological parameters when inferred from model-dependent and -independent probes opened the door for a new paradigm. In this talk, I will address whether (part of) the cosmological tensions can be attributed to missing physics in the standard model. In particular I will focus on tests of different models with interactions between dark energy and dark matter.
