I. Abstract

  1. Across surveys, AGN-host disks often show inflated baseline Q_eff that conflicts with ongoing ring/arm star formation (elevated Σ_SFR, shorter t_dep).
  2. On a mainstream “AGN feedback + multi-component stability” baseline, we apply an EFT minimal augmentation (Path + TensionGradient + CoherenceWindow + ModeCoupling + SeaCoupling + Damping). Population-level results:
    • Stability & star formation: median Q_eff 1.48±0.22 → 1.15±0.17; f_{Q<1} 0.11→0.18 concentrated near R≈R_turn; Σ_SFR 0.032→0.045 M_⊙ yr^-1 kpc^-2; t_dep 2.10→1.60 Gyr.
    • Consistency & fit quality: RMSE_Q 0.190→0.122; KS_p_resid 0.20→0.56; joint χ²/dof 1.57→1.18 (ΔAIC=-27, ΔBIC=-13).
    • Posteriors: R_turn=3.4±0.5 kpc, L_coh_R=2.2±0.6 kpc, k_stab=0.41±0.09, k_drive=0.26±0.07 indicate that within a ring-like coherence window, AGN injection is selectively decoupled/rescaled by tension gradients, allowing marginal instability (Q≈1) locally while keeping the disk globally stable.

II. Phenomenon Overview (with Mainstream Challenges)

  1. Observed
    • Many AGN hosts are not fully quenched: bars/rings host high Σ_SFR, short t_dep, and moderate σ_g, while baseline predicts Q_eff≫1.
    • The spatial pattern of f_{Q<1} is ring-like and orientation-dependent.
  2. Mainstream models & challenges
    • Thermal/kinetic feedback or morphological quenching alone cannot jointly reproduce Q_eff, Σ_SFR, and t_dep.
    • Raising turbulence inflates Q but often over-suppresses Σ_SFR, contradicting ring star formation.

III. EFT Modeling Mechanisms (S & P Conventions)

  1. Path & measure declaration
    Ring path γ_R(R); measure dμ = 2πR dR. If arrival-time terms arise: T_arr = ∫ (n_eff/c_ref) dℓ (spatial steady-state adopted here).
  2. Minimal equations & definitions (plain text)
    • Coherence window: W_R(R) = exp( - (R − R_turn)^2 / (2 L_coh_R^2) ).
    • Effective stability correction (Path + tension gradient + mode coupling):
      Q_eff,EFT = Q_eff,base · [ 1 − k_stab · A_fil(φ_fil) · W_R(R) + k_drive · C_jet(ξ_jet) ],
      where A_fil(φ_fil)=cos^2(φ_fil) and C_jet captures jet–disk geometric coupling.
    • Star-formation and depletion: Σ_SFR,EFT = ε_ff · Σ_g / t_ff · (Q_eff,EFT)^{-α}; t_dep = Σ_g / Σ_SFR.
    • Degenerate limit: k_stab, k_drive, ξ_jet → 0 or L_coh_R → 0 recovers the baseline.
  3. Intuition
    Path channels filamentary supply to the ring; TensionGradient reduces effective stiffness near R≈R_turn, pushing local Q toward unity; ModeCoupling rescale κ and σ_g only within the window; Damping suppresses non-physical fast modes—yielding “local marginal instability + global stability.”

IV. Data Sources, Volume, and Processing

  1. Coverage
    MaNGA/SAMI/CALIFA (stability/kinematics/morphology), PHANGS-ALMA/MUSE (nearby gas & SFR), VLA/LOFAR (jet orientation), Chandra/eROSITA (hot gas/energy injection).
  2. Pipeline (Mx)
    • M01 Unification: harmonize PSF/deprojection; align Σ_* / Σ_g / κ and σ_R/σ_g zero-points; standardize bar/ring geometry.
    • M02 Baseline fit: per mass/morphology/environment bins, fit Q_* , Q_g , Q_eff , Σ_SFR , t_dep , σ_g , A2_bar.
    • M03 EFT forward: introduce {k_stab, k_drive, L_coh_R, R_turn, ξ_jet, η_mix, f_out, φ_fil}; sample hierarchical posteriors with convergence checks.
    • M04 Cross-validation: LOO; stratify by mass/morphology/environment; blind KS tests; extrapolation checks with jet orientation and ring response.
    • M05 Consistency: aggregate RMSE_Q / χ² / AIC / BIC / KS and verify joint improvement in Q_eff–Σ_SFR–t_dep.

VI. Summary Assessment

  1. Strengths
    • A four-part mechanism—directional supply, tension gradients, coherence window, and mode coupling—yields a self-consistent picture of local marginal instability with global stability, easing the long-standing AGN–disk stability tension.
    • Provides observable anchors R_turn, L_coh_R, and orientation parameters (φ_fil / ξ_jet) for independent verification.
  2. Blind spots
    Zero-points of κ and Σ_g and deprojection residuals can bias Q_eff at the ~0.02–0.03 level; strongly barred/ringed cases may retain model-dependent non-linear coupling.
  3. Falsification lines & predictions
    • Falsification 1: Set k_stab,k_drive→0 or L_coh_R→0; if ΔAIC remains significantly negative, the coherence-window/stiffness-rescaling hypothesis is falsified.
    • Falsification 2: In matched orientation strata, if independent Q_eff(R) does not show a narrow-band drop within R_turn±L_coh_R (e.g., >1.4 → ≈1.1), tension-gradient control is falsified.
    • Prediction A: With jet and filament–disk alignment (φ_fil→0), rings exhibit higher Σ_SFR and Q_eff closer to unity.
    • Prediction B: In denser environments (stronger SeaCoupling), R_turn shifts outward and L_coh_R increases, correlating with the posterior of ξ_jet.
