I. Abstract


II. Observation Phenomenon Overview

  1. Observables & Definitions
    • Deflection & offset: δφ_res(R), ΔR_res.
    • Localization consistency: ε_res (resonance localization error), S_cons (consistency score).
    • Phase & locking: ∂φ/∂R, L_lock.
    • Spectral structure: Δf ≡ f_+ − f_- and mode number m confidence.
    • Warp refraction: χ_warp (bending of resonance tracks due to thickness/warp).
  2. Unified Fitting Convention (Axes & Declaration)
    • Observable axis: {δφ_res, ΔR_res, ε_res, S_cons, ∂φ/∂R, L_lock, Δf, χ_warp} and P(|target−model|>ε).
    • Medium axis: Sea / Thread / Density / Tension / Tension Gradient (weights for gas–star two-phase coupling, bar–spiral interface, and outer-disk tension gradients).
    • Path & Measure Declaration: resonance features propagate along gamma(ell) with measure d ell; energy accounting uses ∫ J·F dℓ coupled to the frequency surface Ω, κ; all equations use backticks; SI units apply.

III. EFT Modeling Mechanics (Sxx / Pxx)

  1. Minimal Equation Set (plain text)
    • S01: δφ_res ≈ δφ0 · RL(ξ; xi_RL) · [1 + γ_Path·J_Path + k_SC·(psi_bar+psi_spiral) + k_STG·G_env − k_TBN·σ_env].
    • S02: ΔR_res ≈ α1·psi_bar + α2·psi_spiral − α3·eta_Damp + α4·theta_Coh.
    • S03: L_lock ≈ Φ(θ_Coh, psi_bar, psi_spiral); Δf ≈ β1·k_STG + β2·xi_RL − β3·eta_Damp.
    • S04: χ_warp ≈ ω1·psi_warp + ω2·zeta_topo.
    • S05: ε_res ≈ ε0 · [1 − θ_Coh + k_TBN·σ_env]; S_cons ≈ S0 · [1 + beta_TPR·psi_bar].
    • S06: J_Path = ∫_gamma (∇Φ_eff · d ell)/J0, where Φ_eff absorbs Sea/Thread/Density/Tension terms.
  2. Mechanistic Highlights (Pxx)
    • P01 · Path/Sea Coupling: γ_Path×J_Path with k_SC drives bar–arm phase lag → deflection.
    • P02 · STG/TBN: STG twists the f(Ω, κ) surface; TBN sets peak-split and localization noise floors.
    • P03 · Coherence Window/RL: caps deflection and locking in high-Q regions.
    • P04 · TPR/Topology/Recon: endpoint rescaling and topological re-shaping modulate outer-disk tension gradients contributing to ΔR_res, χ_warp.

IV. Data, Processing & Result Summary

  1. Data Sources & Coverage
    • Platforms: MW & external IFU/HI/CO velocity fields, seismology frequency distributions, bar/spiral morphology, ΛCDM controls, selection-function Monte Carlo.
    • Ranges: R ∈ [1, 18] kpc; mode number m ∈ {1,2,3,4}; bar corotation ratio ℛ=R_CR/R_bar ∈ [1.0, 1.6].
    • Hierarchies: host/environment × morphology (bar strength, arm symmetry) × instrument systematics.
  2. Preprocessing Pipeline
    • Deprojection & systematics: unify inclinations/PAs, instrument response, and rotation-curve baselines.
    • Frequency-surface construction: derive initial ILR/CR/OLR tracks from Ω(R), κ(R).
    • Time–frequency extraction: HHT to obtain Δf, m and detect change points.
    • Geometry fitting: polar field maps + EIV/TLS to estimate δφ_res, ΔR_res, ∂φ/∂R.
    • Hierarchical Bayes: host/environment parameter sharing; Gelman–Rubin and IAT for convergence.
    • Robustness: k=5 cross-validation, leave-one-host, and systematics injection–recovery.

VI. Summative Assessment

  1. Strengths
    • The multiplicative structure (S01–S06) jointly models deflection/offset, locking/splitting, and refraction, with physically interpretable parameters and testable covariances with morphology/environment.
    • Mechanism identifiability: significant posteriors for γ_Path/k_SC/k_STG/k_TBN/β_TPR/θ_Coh/η_Damp/ξ_RL/ψ_bar/ψ_spiral/ψ_warp/ζ_topo separate bar–spiral coupling, outer-disk warp, and environmental tensors.
    • Operational value: sample selection by ψ_bar, ψ_spiral and G_env optimizes SNR for resonance-band deflection.
  2. Blind Spots
    • Strongly perturbed merger phases likely involve non-Markovian L-transfer, calling for memory kernels / fractional terms.
    • Under low completeness, selection functions can decohere deflection signals; stronger forward modelling and hierarchical priors are required.
  3. Falsification Line & Observational Suggestions
    • Falsification line: see front-matter falsification_line.
    • Suggestions:
      1. Bar-end sweeps: densely sample the bar–arm junction to measure environmental slopes of δφ_res(R) and ΔR_res.
      2. Frequency-surface mapping: refine Ω(R), κ(R) reconstruction, track time variability of Δf and m.
      3. Warp control experiment: stratify by ψ_warp to isolate contributions to χ_warp.
      4. Systematics controls: compare with mainstream controls under identical selection functions; run leave-one-host ΔAIC/ΔBIC/ΔRMSE tests.
