This study examines interacting quintessence dark energy models and their observational constraints for a general parameterization of the quintessence potential, which encompasses a broad range of popular potentials. Four different forms of interactions are considered. The analysis is done by expressing the system as a set of autonomous equations for each interaction. The Bayesian Model Comparison has been used to compare these models with the standard Lambda Cold Dark Matter ({\Lambda}CDM) model. Our analysis shows positive and moderate evidence for the interacting models over the {\Lambda}CDM model.

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

    astro-ph.CO 2025-10 accept novelty 6.0

    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. Bouncing Cosmology in Interacting Scalar-Torsion Gravity

    gr-qc 2025-08 conditional novelty 3.0

    Two interacting scalar-torsion models are shown, by tuned numerical construction, to host a matter bounce with phantom equation of state and NEC violation at the bounce epoch.
