CDN-331: The Strong Lens — GCFT confronts galaxy-scale strong lensing via SLACS

Key Points

The study aims to test the predictions of General Coherence Field Theory against observed galaxy-scale strong gravitational lenses.
Analyzed 20 galaxy-scale strong gravitational lenses from the SLACS survey.
Compared model-independent enclosed mass measurements at the Einstein radius.
Evaluated ν(x) against empirical data to assess the theoretical model's accuracy.
Found a systematic under-prediction with a median mass ratio M_GCFT/M_Ein of 0.415.
Identified a high dark matter fraction with R_DM values of 0.94 (Chabrier IMF) and 0.81 (Salpeter IMF).
Revealed ν(x) ~ 1.09, indicating structural irrelevance in the tested context.

Abstract

We confront General Coherence Field Theory's interpolating function ν (x) = 1 + nBE (√x) against 20 grade-A galaxy-scale strong gravitational lenses from the SLACS survey (Bolton+08, Auger+09/10). Each system provides a model-independent enclosed mass at the Einstein radius. At g/a₀ ~ 6, ν (x) ~ 1. 09 — structurally irrelevant. Result: systematic FAIL (median MGCFT/MEin = 0. 415, all 20 under-predicted). Scale ladder diagnostic: RDM = 0. 94 (Chabrier IMF) / 0. 81 (Salpeter IMF) — the highest dark matter fraction of any tested GCFT regime. D13 opened: derive the ν (x) -to-κ-proxy transition. CDN-332 pre-registered: apply cluster κ-proxy to SLACS ETGs. Archive contains Art Edition PDF, computation script, build script, and full per-lens results JSON.
