Constraining interacting dark energy models with latest cosmological observations

The local measurement of H 0 is in tension with the prediction of Λ cold dark matter model based on the Planck data. This tension may imply that dark energy is strengthened in the late-time Universe. We employ the latest cosmological observations on cosmic microwave background, the baryon acoustic o...

Description
Summary:The local measurement of H 0 is in tension with the prediction of Λ cold dark matter model based on the Planck data. This tension may imply that dark energy is strengthened in the late-time Universe. We employ the latest cosmological observations on cosmic microwave background, the baryon acoustic oscillation, large-scale structure, supernovae, H(z) and H 0 to constrain several interacting dark energy models. Our results show no significant indications for the interaction between dark energy and dark matter. The H 0 tension can be moderately alleviated, but not totally released.
