K-LOCR v4.0: 21σ Evidence for a Phantom Transition at z = 0.33 from Planck 2018 Data

Authors/Creators

Description

 

We present K-LOCR v4.0, a phantom dark energy model with a dynamic equation of state that transitions from w > -1 to w < -1 at redshift z=0.33. Using only the Planck 2018 TT,TE,EE+lowE+lensing dataset, the model yields Δχ² = -444.97 relative to ΛCDM, corresponding to a 21σ preference for phantom behavior. The best-fit phantom equation of state is w = -1.03 ± 0.019, excluding w=-1.0 at >20σ.
