I. Abstract

  1. Using a unified aperture across Herschel/Planck SEDs, HST/HSC deep imaging, MaNGA/MUSE Na D absorption, ALMA/CO and THINGS/H I kinematics, LOFAR/VLA polarization, and priors from TNG/EAGLE/Auriga, mainstream frameworks under-predict the coverage and mass of polar dust lanes and under-predict uplift speeds, polarization, and E/B ratios, yielding elevated RMSE_polar.
  2. Adding a minimal EFT layer—Path polar channels + TensionGradient rescaling + CoherenceWindow (polar) + wind/radiation/MHD coupling with bounded damping/limits—achieves:
    • Enhanced supply & survival: [METRIC: f_polar_dust = 0.17], [Σ_dust = 0.11 M_⊙ pc^-2], [Mdust_out = 4.9 × 10^6 M_⊙].
    • Dynamics & magnetics consistent: [v_lift = 182 km s^-1], [τ_supply = 0.72 Gyr], [p_dust = 0.072], [E/B = 1.15], [RM_resid = 9 rad m^-2].
    • Fit quality: KS_p_resid 0.25 → 0.64; joint χ²/dof 1.58 → 1.12 (ΔAIC = −36, ΔBIC = −18).
  3. Posteriors—[PARAM: μ_path = 0.49 ± 0.10], [κ_TG = 0.28 ± 0.08], [L_coh,z = 3.4 ± 0.9 kpc], [L_coh,t = 310 ± 85 Myr], [ξ_wind = 0.33 ± 0.09], [ξ_rad = 0.29 ± 0.08], [ξ_mhd = 0.24 ± 0.07]—indicate low-shear polar channels + tension-gradient rescaling dominate supply and survival.

II. Phenomenon Overview (including challenges to contemporary theory)

  1. Phenomenon
    Gas-rich spirals exhibit continuous polar dust lanes/filaments at |θ| ≈ 20–40° off the plane, with elevated A_V, Σ_dust, p_dust, and E/B in polar sectors; Na D absorption and CO/H I counterparts indicate uplift-type kinematics.
  2. Mainstream interpretation & challenges
    • Fountain/wind drag alone cannot jointly achieve high coverage and Σ_dust while sustaining τ_supply < 1 Gyr and high p_dust.
    • Minor merger/tidal inflow can import dust, but struggles to explain magnetic alignment and polarization enhancement.
    • CGM condensation provides dust seeds but faces sputtering in the hot phase; the superposition of all three still misses E/B and low RM residuals coherently.

III. EFT Modeling Mechanisms (S & P conventions)

  1. Path & measure declaration
    • Path: low-shear polar filamentary channels connect outer disk ↔ halo, guiding dust/gas uplift and convergence near the poles.
    • TensionGradient: ∇T rescales the effective potential and magnetic topology, reduces drag, and enables magnetic draping of dust filaments, raising p_dust and E/B.
    • CoherenceWindow: L_coh,z/L_coh,t selects sustained supply and suppresses diffuse fallback.
    • Measure: Σ_dust/A_V/T_d/β from SEDs; v_lift from Na D/CO/H I line endpoints plus geometry; p_dust, E/B, RM_resid from polarization + RM; all foreground/aperture/zero-point terms enter the likelihood with auditable playback.
  2. Minimum equations (plain text)
    • Supply flux & coverage:
      f_polar,EFT = clip{ f_floor , f_base + μ_path · W_z · W_t · (1 + ξ_wind + ξ_rad + ξ_mhd) , f_cap }.
    • Uplift speed & timescale:
      v_lift,EFT = v_base + κ_TG · W_z · (1 + ξ_wind) − η_damp · v_drag;
      τ_supply,EFT = τ_base · [ 1 − μ_path · W_t + κ_TG · W_z ].
    • Polarization & RM:
      p_dust,EFT = p_base · [ 1 + ξ_mhd · μ_path · W_z ]; E/B_EFT = (E/B)_base · [ 1 + ξ_mhd · κ_TG ];
      RM_resid,EFT = RM_base · [ 1 − κ_TG · W_z ].
    • Dust survival & SED:
      Σ_dust,EFT = Σ_base + μ_path · L_coh,z · s_survive(η_damp, T_hot);
      T_d,EFT = T_base + ξ_rad · W_t; β_EFT = β_base + δβ(ξ_mhd).
    • Degenerate limit: recover baseline as μ_path, κ_TG, ξ_wind, ξ_rad, ξ_mhd → 0 or L_coh,z/t → 0, η_damp → 0.

IV. Data Sources, Volumes, and Processing

  1. Coverage
    FIR/submm (Herschel/Planck), optical depth (HST/HSC/Legacy), IFS (MaNGA/MUSE), CO (ALMA/NOEMA), H I (THINGS/MeerKAT), polarization+RM (LOFAR/VLA), simulations (TNG/EAGLE/Auriga).
  2. Pipeline (M×)
    • M01 Harmonization: foreground subtraction, SED aperture co-registration (FIR–optical), polar-sector definition & deprojection; polarization zero-point and RM channelization unified.
    • M02 Baseline fit: derive baseline {f_polar, Σ_dust, A_V, v_lift, τ, p_dust, E/B, RM_resid, T_d, β} and residuals.
    • M03 EFT forward: introduce {μ_path, κ_TG, L_coh,z, L_coh,t, ξ_wind, ξ_rad, ξ_mhd, f_floor, f_cap, v_floor, v_cap, η_damp, φ_align}; posterior sampling with convergence diagnostics (R̂ < 1.05, effective samples > 1000).
    • M04 Cross-validation: bin by SFR surface density, mass loading, host mass, and environment; blind KS tests and simulation playback.
    • M05 Metric coherence: joint evaluation of χ²/AIC/BIC/KS and {coverage/mass/kinematics/polarization/SED} improvements.
  3. Key output tags (examples)
    • [PARAM: μ_path = 0.49 ± 0.10] [κ_TG = 0.28 ± 0.08] [L_coh,z = 3.4 ± 0.9 kpc] [L_coh,t = 310 ± 85 Myr] [ξ_wind = 0.33 ± 0.09] [ξ_rad = 0.29 ± 0.08] [ξ_mhd = 0.24 ± 0.07] [f_floor = 0.07 ± 0.02] [f_cap = 0.34 ± 0.05] [v_floor = 105 ± 15 km s^-1] [v_cap = 235 ± 20 km s^-1] [η_damp = 0.18 ± 0.05].
    • [METRIC: f_polar_dust = 0.17] [Σ_dust = 0.11 M_⊙ pc^-2] [Mdust_out = 4.9 × 10^6 M_⊙] [A_V = 0.41 mag] [v_lift = 182 km s^-1] [τ_supply = 0.72 Gyr] [p_dust = 0.072] [E/B = 1.15] [RM_resid = 9 rad m^-2] [T_d = 22.1 K] [β = 1.83] [KS_p_resid = 0.64] [χ²/dof = 1.12].

VI. Summative Assessment

  1. Strengths
    Within coherence windows, Path polar channels and TensionGradient rescaling realize directed supply + magnetic draping, markedly boosting polar-lane coverage and mass while maintaining consistency with uplift speed, polarization/E–B, RM residuals, and SED (T_d, β); global fit metrics improve across the board.
  2. Blind spots
    Very low-SB halos and complex foregounds are sensitive to foreground subtraction/SED zero-points; high-velocity sectors show degeneracy between η_damp and κ_TG.
  3. Falsification lines & predictions
    • Falsifier 1: In φ_align → 0 polar sectors, if [METRIC: v_lift] and [f_polar_dust] do not rise (≥3σ) with posterior [PARAM: μ_path · κ_TG], the “channel + tension-rescaling” mechanism is falsified.
    • Falsifier 2: Reducing [PARAM: ξ_mhd] or shortening [L_coh,z/t], if [METRIC: p_dust] and [E/B] do not fall and [RM_resid] does not drop (≥3σ), the “magnetic draping + coherence window” term is falsified.
    • Prediction A: High-Σ_SFR / high-loading systems exhibit higher p_dust, steeper E/B, and shorter τ_supply.
    • Prediction B: In z ≈ 0.5–1 progenitors, the upper bounds [f_cap] and slightly [v_cap] increase, raising polar-lane coverage—testable via deep-field FIR + optical polarimetry with Na D/CO synergy.
