- <p>This document introduces a quantitatively testable interpretation of galactic disks and halos as weak radial resonance-gradient structures.</p> <p>An operational mismatch proxy,</p> <p>Δf(r) = Ω_orb(r) − κ(r)/2,</p> <p>is defined directly from observable rotation curves and epicyclic frequency profiles. This proxy can be computed from observational data, mass models, or simulation outputs.</p> <p>A minimal radial dynamical model is developed showing that local minima in Δf(r) can bias orbital density and produce weak shell or ring layering. During merger events, time-dependent gravitational potentials amplify this structuring.</p> <p>The manuscript provides:</p> <p>• An operational and computable definition of the resonance mismatch</p> <p>• A minimal dynamical trapping model</p> <p>• A quantitative shell amplitude normalization</p> <p>• A merger-age exponential decay prediction</p> <p>• Order-of-magnitude scaling examples</p> <p>• Observability thresholds for density and kinematic modulation</p> <p>• A full falsifiable observational and simulation pipeline</p> <p>A key quantitative prediction is:</p> <p>A_shell(t) = A0 exp(−t / τ_relax),</p> <p>with τ_relax ≈ 1 / κ(r).</p> <p>This allows direct testing using merger-age binned galaxy samples.</p> <p>The full radial profile Δf(r) is interpreted as a galaxy’s dynamical resonance fingerprint, reflecting its formation and merger history.</p> <p>The hypothesis is falsifiable if shell regularity, kinematic modulation, and age evolution are fully reproduced by standard collisionless N-body models without additional resonance-layer amplification.</p> <p>Merger systems serve as the decisive laboratory for testing the model.</p> <p>This document is conceptual and test-oriented, not a data release.</p>
