Analysis code and data for "Do Photons and Matter Trace the Same Cosmic Geometry? A Falsifiable Test and Current Constraints"

Résumé fourni par la source

Complete, reproducible analysis supporting the manuscript "Do Photons and Matter Trace the Same Cosmic Geometry? A Falsifiable Test and Current Constraints" (T. F. Parente). Includes the Markov-chain Monte Carlo analysis code and the compiled observational data files (31 cosmic-chronometer H(z) points; 7 radial BAO points from BOSS DR12 and DESI DR1, converted with the Planck sound horizon; 14 binned Pantheon+ supernova distance moduli). Running the provided script reproduces the paper's central result, a constraint on the disformal optical bias parameter consistent with zero (alpha = 0.027 +0.034/-0.020; alpha < 0.089 at 95%). See the included README for the exact commands and data provenance.
