Pointer Architecture: A Constrained Information-Geometric Model of Galactic Rotation Curves

Аннотация

We compare three information-geometric models of galactic rotation on the 171-galaxy SPARC sample: unconstrained pointer, constrained pointer (with a physical prior on halo extent), and a standard NFW baseline. The constrained pointer wins AIC on 60 of 171 galaxies and shows a positive partial correlation between halo extent and inferred information mass (ρ = +0.19, q_FDR = 0.04). Four of six residual-structure features correlate with galactic age at FDR-controlled significance. A full reproducibility pipeline — code, data, and fit diagnostics — is released alongside the preprint.

Предсказания и фальсификаторы

1. Constrained pointer fit quality improves systematically with galactic age.
2. Residual-structure features at large radii should track halo concentration, not stellar mass.
3. Low-surface-brightness galaxies should show larger pointer-vs-NFW AIC gaps.
4. Independent samples (LITTLE THINGS, THINGS) should reproduce the ρ direction on halo extent.
5. Falsifier: if the ρ sign flips on an independent age-controlled resample, the model fails.
6. Falsifier: if AIC-preferred galaxies correlate with survey artefacts rather than age, the result is observational.
7. Falsifier: if reproducibility pipeline yields materially different fits under reasonable re-parameterisation, results are over-fit.
