Interacting dark energy in a closed universe

ABSTRACT Recent measurements of the Cosmic Microwave Anisotropies power spectra measured by Planck satellite show a preference for closed universe at more than $99 {{\ \rm per\ cent}}$ confidence level (CL). Such scenario is however in disagreement with several low redshift observables, including luminosity distances Type Ia supernovae. Here we that interacting dark energy (IDE) models can ease discrepancies between and supernovae data Universe, leading to both coupling curvature different from zero above 99 per cent CL. Therefore IDE cosmologies remain as very appealing scenarios, they provide solution number observational tensions fiducial cosmologies. The results presented here strongly favour broader analyses cosmological data, suggest relaxing usual flatness vacuum assumptions lead much better agreement among theory observations.
