abstract

It has been intensively discussed if modifications in the dynamics of the Universe at late times is able or not to solve the $H_0$ tension. On the other hand, it has also been argued that the $H_0$ tension is actually a tension on the supernova absolute magnitude $M_B$. In this work, we robustly constraint $M_B$ using Pantheon Supernovae Ia (SN) sample, Baryon Acoustic Oscillations (BAO), and Big Bang Nucleosynthesis (BBN) data, and assess the $M_B$ tension by comparing three theoretical models, namely the standard $\Lambda$CDM, the $w$CDM and a non-gravitational interaction (IDE) between dark energy (DE) and dark matter (DM). We find that the IDE model can solve the $M_B$ tension with a coupling different from zero at 95\% CL, confirming the results obtained using a $H_0$ prior.

  1. BAO miscalibration cannot rescue late-time solutions to the Hubble tension

    astro-ph.CO 2025-10 accept novelty 6.0 of 10

    Even after rescaling BAO data to prefer H0≈73 km/s/Mpc, none of six tested late-time dark-energy models can resolve the Hubble tension once unanchored SNeIa and CMB geometry are included.

  2. Robust Preference for Dark Sector Interactions

    astro-ph.CO 2026-01 conditional novelty 5.0 of 10

    Interacting dark matter–dark energy models fit DESI BAO and CMB data as well as evolving-dark-energy (CPL) models, with a coupling preference that persists under DES-Dovekie supernova recalibration.

  3. Sign Switching in Dark Sector Coupling Interactions as a Candidate for Resolving Cosmological Tensions

    astro-ph.CO 2025-01 conditional novelty 5.0 of 10

    A sign-switching dark-sector coupling, fitted to CMB, DESI BAO, and supernova data, can simultaneously raise H0 and lower S8, but the preference over LambdaCDM depends on using SH0ES-calibrated supernovae.

  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.
