Preprocessing Workflow

  1. Ring mass distribution and radiation field corrections, separating outflow and ionization patterns.
  2. Joint modeling of density wave responses and ring amplitudes, identifying wave propagation speeds and fluctuations.
  3. Calculating inner and outer slope differences and accurately locating ring radii.
  4. Uncertainty propagation via total-least-squares + errors-in-variables.
  5. Hierarchical Bayesian MCMC by galaxy type/environment/ring layer; convergence via R̂ and IAT; k=5 cross-validation.

VI. Summative Assessment

Strengths

  1. Unified multiplicative structure (S01–S05) captures the co-evolution of R_ring/δρ_ring/E_ism/A_ring with interpretable parameters, actionable for ring formation and interstellar medium interactions.
  2. Mechanism identifiability: Significant posteriors across γ_Path, k_SC, k_STG, k_TBN, β_TPR, θ_Coh, η_Damp, ξ_RL, ζ_topo separate contributions from density waves, rings, and the interstellar medium.
  3. Operational utility: Real-time monitoring of J_Path, σ_env, ψ_ring and ring residuals helps optimize ring propagation speed and radiation field models.

Blind Spots

  1. In high-temperature or low-metallicity galaxies, the interstellar medium's impact on ring formation may show non-linear behavior, requiring further analysis of environmental influences.
  2. Outflow impacts may interfere with ring formation, especially in galaxies with low gas density.

Falsification Line and Experimental Suggestions

  1. Falsification line. If EFT parameters → 0 and the covariance among R_ring/δρ_ring/E_ism/A_ring disappears while mainstream models satisfy ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1%, the mechanism set is falsified.
  2. Experiments.
    • 2D Phase Maps: Plot R_ring/δρ_ring vs A_ring in (r,θ) space to assess environmental effects on ring formation.
    • Tracer Cross-Validation: Joint observations using different tracers to validate ring and density wave interactions.
    • Environmental De-noising: Test the effects of different gas densities on ring intensity to optimize model validation.
