Beyond Type Ia Supernavae:A Multi-Probe Strategy for Testing Cosmological General Relativity(CGR) Against Lambda CDM Using BAO, Cosmic Chronometers, Redshift-Space Distortions, CMB Shift Parameters, and Standard Sirens

Year: 2026

Type: preprint

Abstract: A companion analysis of the Pantheon+SH0ES Type Ia supernova compilation (N=1,701) found no statistically justified preference for Cosmological General Relativity(CGR) over Lambda CDM once model complexity was penalized, and showed that the nominal dipole signal recovered from supernova alone is consistent with known local bulk-flow contamination rather than with CGR's predicted cosmological anisotropy.
