A Fixed–Shape Gravitational Kernel with Baryon–Only Amplitude for Galaxy Rotation Curves

This upload is a complete Version 8 release of the work “A Fixed–Shape Gravitational Kernel with Baryon–Only Amplitude for Galaxy Rotation Curves” (Kyron Damon, 2026). It includes (1) the full manuscript PDF and (2) the accompanying reproducible Python pipeline used to generate the figures and validation statistics reported in the paper. The manuscript proposes a fixed-shape radial response kernel K(R) acting on the baryonic rotation curve v_{\mathrm{bar}}(R), together with a strictly baryon-only amplitude law based only on the maximum baryonic rotation speed v_{\mathrm{bar,max}}. The predictive model produces galaxy rotation curve predictions without per-galaxy tuning. The included pipeline implements the kernel and both amplitude modes (predictive and oracle). It reads SPARC-format rotation curve files (or compatible CSVs), constructs v_{\mathrm{bar}}(R), applies the kernel, and outputs predicted rotation curves, plots, per-galaxy JSON summaries, and an aggregate summary table. This release also includes the full validation outputs from applying the pipeline to the complete SPARC sample (175 galaxies). In predictive mode, the model achieves a median RMS residual of 14.2 km s⁻¹ and a mean RMS residual of 22.6 km s⁻¹ across the sample, without per-galaxy tuning. In oracle mode (best-fit amplitude benchmark), the median RMS residual is 7.8 km s⁻¹ and the mean RMS residual is 15.9 km s⁻¹. These values correspond to the figures and results reported in the manuscript and can be reproduced directly using the included code. This bundle is intended to provide a single, self-contained release: the scientific narrative (paper) plus the executable implementation (pipeline) and the generated outputs supporting the reported claims.
