Cosmological Constraints on Nonphantom Dynamical Dark Energy with DESI Data Release 2 Baryon Acoustic Oscillations: A 3σ+ Lensing Anomaly

We consider a 12-parameter cosmological model with nonphantom dynamical dark energy (NPDDE), where nonphantom implies that the equation of state (EoS) of dark energy (DE), w ( z ) ≥ −1 for all redshifts z . Thus, the DE-EoS covers the parameter space corresponding to the popular single scalar-field...
