Revisiting the evidence for dynamical dark energy: from DES-SN5Y to DES-Dovekie
This cosmology study asks whether apparent evidence for dynamical dark energy survives replacement of DES-SN5Y supernova data with the revised DES-Dovekie compilation alongside DESI DR2 BAO and CMB. Preference over ΛCDM falls substantially and is below 1σ for most models.
