abstract

The local measurement of $H_0$ is in tension with the prediction of $\Lambda$CDM 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 CMB, BAO, LSS, SNe, $H(z)$ 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.

  1. Unifying Early and Late Dark Energy: Dynamical Requirements and Obstructions

    astro-ph.CO 2026-05 unverdicted novelty 7.0 of 10

    Any unified early and late dark energy scenario with a single tracking scalar field requires a potential with three distinct slopes arranged in a steep-steeper-shallow hierarchy.

  2. Hints Beyond $\Lambda$CDM from Barrow and Tsallis Holographic Dark Energy with GO cutoff

    gr-qc 2026-01 conditional novelty 5.0 of 10

    Barrow holographic dark energy with the Granda-Oliveros cutoff fits current background data as well as ΛCDM and shows a weak AIC preference only for the Union3-based dataset combination.

  3. Interacting dark energy in the early 2020s: a promising solution to the $H_0$ and cosmic shear tensions

    astro-ph.CO 2019-08 conditional novelty 5.0 of 10

    An interacting dark energy model with coupling proportional to the dark energy density alleviates the H0 and S8 tensions in Planck 2018 data but is not preferred once BAO and supernova data are included.

  4. Dark Energy Is Not That Into You: Variable Couplings after DESI DR2 BAO

    astro-ph.CO 2025-08 conditional novelty 4.0 of 10

    With DESI DR2 data, one interacting dark sector model with a time-dependent coupling shows a nonzero coupling at more than 95% CL, but Bayesian evidence still favors Lambda-CDM.

  5. Quantifying the impacts of future gravitational-wave data on constraining interacting dark energy

    astro-ph.CO 2019-08 conditional novelty 4.0 of 10

    Adding 1000 simulated Einstein Telescope standard sirens to current CMB, BAO, and supernova data would tighten H0 and matter density constraints by factors of 2 to 3 in four interacting dark energy models, with modest...
