GL8 – Abell 520 (P1–P12)

This simulation models gravitational lensing in the Abell 520 ("Train Wreck") galaxy cluster using both General Relativity (GR) and the Curvature Factor (CF) framework proposed by the Tejera-Ace Standard Model (TASM). Based on the observed arc peak positions (P1–P12) from Jee et al. (2014), we apply a Singular Isothermal Ellipsoid (SIE) lens with external shear and ray-trace each configuration across four curvature gradients: GR baseline (CF 0.0), CF 1.0, CF 2.0, and CF 2.999. The goal is to assess whether curvature gradients can replicate observed lensing behavior without invoking excess dark matter. All simulations use a consistent PSO optimization strategy, and residuals are computed as source-plane displacements in arcseconds. Statistical validation includes KS, Chi², Anderson–Darling, and G-tests with FDR correction. This run complies fully with the TASM Simulation Scrutiny Protocol, including reproducibility, data integrity, and falsifiability. All outputs are archived, hashed, and bundled in a protocol-compliant ZIP for peer audit and publication.
