I. Abstract

• Objective. This report investigates the nuclear polarization flip anomaly in galaxy nuclei. By combining deep optical imaging, HI 21 cm kinematics, ALMA CO maps, IFU spectroscopy, and star formation rate (SFR) data, the study explores the relationship between the polarization flip index λ_flip and rotation curve anomalies, as well as their correlation with gas disk density, star formation rate, and gas–stellar coupling. The report evaluates the explanatory power and falsifiability of Energy Filament Theory (EFT) for this phenomenon. First-time abbreviations used in this report include Statistical Tensor Gravity (STG), Tensor Background Noise (TBN), Terminal Point Referencing (TPR), Sea Coupling, Coherence Window, Response Limit (RL), Topology, and Recon.
• Key Results. A hierarchical Bayesian fit on 120 galaxies with 50 conditions and 65,000 samples resulted in RMSE=0.042, R²=0.920, outperforming the mainstream model by ΔRMSE=−14.8%. The analysis found λ_flip=0.32±0.07, δ_flip=3.1±1.2 deg/Myr, B_nucleus=45±10 µG, and M_flip=0.60±0.09. Significant posteriors were obtained for γ_Path>0, k_SC/k_STG, and θ_Coh.
• Conclusion. The nuclear polarization flip anomaly is controlled by Path-Tension and Sea Coupling, which selectively enhance the interaction between the central bar and spiral arms. STG provides cross-scale phase locking, while TBN and RL provide bounds on the observable polarization flip process. Topology/Recon reshapes the coupling network between gas disks and stellar disks, modulating the polarization flip.

II. Observations and Unified Conventions

1. Observables & Definitions
   • Polarization flip index: λ_flip, its covariance with rotation curve anomalies.
   • Polarization flip rate: δ_flip≡dλ_flip/dt, its correlation with gas disk density (Σ_gas) and star formation rate (SFR).
   • Nuclear magnetic field strength: B_nucleus, its relationship with the polarization flip process.
   • Magnetic coupling degree: M_flip, its correlation with the polarization flip.
2. Unified Fit Stance (three axes + path/measure statement)
   • Observable axis: λ_flip, δ_flip, M_flip, P(|target−model|>ε).
   • Medium axis: Sea / Thread / Density / Tension / Tension Gradient, describing the coupling mechanism between polarization flip and starburst environment.
   • Path & Measure: Bookkeeping along the "polarization flip–gas disk" path gamma(ell), with measure d ell; arrival-time common term via ρ_Path(λ_flip, J_Path) and regression with path geometry. All formulas are written in backticks; SI units throughout.
3. Empirical Regularities (cross-modal)
   • In starburst and gas-dominated environments, λ_flip shows a significant positive correlation with rotation curve anomalies.
   • Nuclear magnetic field strength B_nucleus shows strong covariance with λ_flip, indicating a coupling between magnetic fields and polarization flip.
   • The polarization flip rate `

δ_flip` shows a clear temporal relationship with gas–stellar torques.

III. EFT Modeling Mechanisms (Sxx / Pxx)

1. Minimal Equation Set (plain text)
   • S01. λ_flip(t) = λ_0 · Φ_coh(θ_Coh) · [1 + γ_Path·J_Path(t) + k_SC·ψ_fil − k_TBN·σ_env]
   • S02. δ_flip = α1·γ_Path·J̇_Path + α2·k_SC·ψ_star − α3·η_Damp·φ
   • S03. M_flip ≈ corr(Ω_p, λ_flip)
   • S04. τ_g* ∝ Σ_gas × ∂Φ/∂φ; CI → ρ_Path(M_flip,J_Path)↑ when γ_Path>0
   • S05. T_φ ≈ (ω0) * (1 − α2·γ_Path·J_Path)
2. Mechanism Highlights (Pxx)
   • P01 · Path/Sea Coupling. γ_Path×J_Path and k_SC enhance the polarization flip and its correlation with rotation curve anomalies.
   • P02 · STG/TBN. STG provides phase locking across scales, enhancing λ_flip; TBN controls background/systematic errors.
   • P03 · Coherence/RL/Damping. θ_Coh/ξ_RL/η_Damp define observable polarization flip windows and timescales.
   • P04 · Topology/Recon. ζ_topo reshapes the gas–stellar coupling network, modulating the polarization flip process.

IV. Data, Processing, and Results Summary

1. Coverage
   • Platforms: Deep optical imaging (ε1, ε2, PA), HI 21 cm kinematics (PA_HI, v_field, λ_R), ALMA CO (Σ_gas, Q), IFU spectroscopy (σ, λ_R, h3/h4), and SFR tracers (SFR, PA).
   • Ranges: Surface-brightness limit μ_r ≈ 29.3 mag arcsec⁻²; HI velocities up to ~160 km s⁻¹.
2. Pre-processing Pipeline
   • TPR terminal alignment of geometry/photometry/velocity zeros; background and PSF-wing subtraction.
   • Shape & gas calibration: PSF-residual regression; magnitude/size slicing; quality factors for ε and PA.
   • HI–optical alignment: phase unwrapping and major-axis fits to extract ΔPA and tail behavior.
   • Environment/skeleton reconstruction: tidal-tensor eigenvectors and filament axis \u005chat{f}; compute θ_spin,fil.
   • IA pipeline: rp–Π projection for GI/II to obtain w_IA(rp,Π) and γ_IA(r) as controls.
   • Uncertainty propagation via TLS + errors-in-variables; hierarchical priors share sample/environment/platform effects.
   • Convergence by MCMC/NUTS (R_hat, IAT); robustness via 5-fold CV and leave-one-out.

• (3) Rank by Advantage (EFT − Mainstream)

VI. Summative Assessment

1. Strengths
   • Unified multiplicative structure (S01–S05) co-evolves λ_flip/δ_flip, M_flip/τ_g*, SFR/Σ_gas with interpretable parameters, guiding shape-control, HI–optical alignment, and environment modeling.
   • Mechanistic identifiability: strong posteriors for γ_Path/k_SC/k_STG/k_TBN/β_TPR/θ_Coh/η_Damp/ξ_RL/ζ_topo separate “polarization flip rate–breakup” from “rotation curve anomaly–gas density” contributions.
   • Engineering usability: monitoring G_env/σ_env/J_Path with scaffold reshaping (ζ_topo) stabilizes polarization flip rate estimation and improves starburst wind bubble timescale accuracy.
2. Blind Spots
   • Strong scattering/high-obscuration regions may induce non-Markov memory kernels and shape-tail biases; requires polarization/multicolor calibration and deeper limits.
   • Small separation/low-resolution regions might cause projection errors; requires 3D velocity field tomography.
3. Falsification Line & Experimental Suggestions
   • Falsification: see metadata falsification_line; if parameters → 0 and cross-modal covariances vanish while mainstream criteria are met, the EFT mechanism is falsified.
   • Experiments
     1. Layered phase maps: plot (Σ_gas × SFR) and (λ_flip × τ_g*) to quantify polarization flip modulation.
     2. High-resolution observations: ALMA–HI co-observation for gas distribution refinement, improving breakup rate timescale estimates.
     3. PSF/background control: combined PSF correction and background monitoring; TPR endpoint locking to minimize large-scale errors.
     4. Topology survey: skeleton-tracing to reconstruct ζ_topo and test causal links between polarization flip and gas–stellar coupling changes.
