# 2021-H0 odyssey: closed, phantom and interacting dark energy cosmologies

@article{Yang20212021H0OC, title={2021-H0 odyssey: closed, phantom and interacting dark energy cosmologies}, author={Weiqiang Yang and Supriya Pan and Eleonora Di Valentino and Olga Mena and Alessandro Melchiorri}, journal={Journal of Cosmology and Astroparticle Physics}, year={2021}, volume={2021} }

Up-to-date cosmological data analyses have shown that (a) a closed universe is preferred by the Planck data at more than 99% CL, and (b) interacting scenarios offer a very compelling solution to the Hubble constant tension. In light of these two recent appealing scenarios, we consider here an interacting dark matter-dark energy model with a non-zero spatial curvature component and a freely varying dark energy equation of state in both the quintessential and phantom regimes. When considering…
