abstract

Recently, we give the robust $\sim2\,\sigma$ evidences of dynamical dark matter and beyond $2\,\sigma$ signals of the coexistence of dynamical dark matter and dynamical dark energy using current cosmological observations [1]. Here we propose the quintessence dark matter model to explain the evolution of dark matter over time on cosmic scales. Interestingly, we find that the exponential quintessence is likely the origin of such an evolution.

  1. ACT DR6 Leads to Stronger Evidence for Dynamical Dark Matter

    astro-ph.CO 2025-06 reject novelty 4.0 of 10

    A joint analysis of ACT DR6, DESI DR2 BAO and DESY5 supernovae finds a 3.4σ preference for dark matter with an evolving equation of state, but the significance is sensitive to model choice and data selection.
