A Novel Phenomenological Ansatz for Dynamical Dark Energy: Resolving Cosmological Tensions via Cosmic-Time Exponentials

We introduce a novel three-parameter phenomenological ansatz for the dark energy equation of state (EoS) parametrized as w(t) = w_inf - exp(K t)/V_0, where t denotes the cosmic time measured relative to the current epoch. We confront this formulation against the latest Baryon Aco...
