Observational Constraints on the Nilkanth Parameterization using Joint CMB, Supernovae, and Baryon Acoustic Oscillations Data

This paper establishes the definitive observational testing framework and statistical methodology for the Nilkanth Equation of State (w(z)). It outlines the precise computational and parameter estimation pipeline required to constrain the model's tracking constant (\alpha) against the world's premier space telescope repositories. High-Redshift Anchor: Details how early-universe Hubble Friction locks the scalar field at its potential apex (w \to -1), guaranteeing a flawless statistical fit to the
