A phenomenological redshift-dependent SNIa magnitude correction shows no evidence in ΛCDM but is preferred at 4.3σ with dynamical dark energy, reducing Hubble tension to 1.5σ.
Establishes a parameter mapping from anisotropic matter black holes to nonlinear electrodynamics black holes, recovering known solutions like dark matter and scalar hair cases and extending to rotating extremal limits.
A new q(z) model with radiative term fits CC, SNIa, HIIG and QSO data to indicate reduced late-time acceleration and earlier transition than LambdaCDM.
