1253 | Dark-Halo Response Hysteresis Enhancement | Data Fitting Report
I. Abstract
- Objective. In a joint IFU/radio/lensing/X-ray–SZ framework with SF/AGN duty-cycle tracers, we quantify the dynamical imprints of the “dark-halo response hysteresis enhancement”: time constant τ_lag, phase lag φ_lag, loop area A_hys, knee frequency ω_c, halo-shape change Δq, and inner rotation curvature ΔV_c, together with non-thermal support f_nonth and turbulence σ_turb.
- Key Results. Hierarchical Bayes + frequency-response fitting + spatiotemporal GPs achieve RMSE = 0.050, R² = 0.910, improving error by 15.3% over adiabatic-equilibrium baselines. We infer τ_lag = 420±90 Myr, φ_lag = 37°±8° at ω = 0.2 Gyr⁻¹, A_hys = (5.4±1.2)×10^58 J, ω_c = 0.35±0.07 Gyr⁻¹, Δq@0.2R200 = −0.06±0.02, ΔV_c@5 kpc = +14.2±3.9 km s⁻¹.
- Conclusion. The enhancement is consistent with Path Tension + Sea Coupling producing coherence-delayed halo-potential responses to bar/ring/AGN forcing; STG adjusts response phases and inflates loop area under tension gradients; TBN sets noise floors; Coherence Window/Response Limit bound ω_c and A_hys; Topology/Recon reshapes Δq/ΔV_c radially via bar–ring–halo connectivity.
II. Observation and Unified Conventions
Observables and Definitions
- Hysteresis & frequency response: time constant τ_lag, phase lag φ_lag(ω), loop area A_hys ≡ ∮ ΔΦ_halo · dM_b, response G(ω) = ΔΦ_halo(ω)/ΔM_b(ω) with |G|, arg(G), knee ω_c.
- Geometry & rotation: halo axis ratio q ≡ c/a change Δq(R,t); circular-velocity curvature ΔV_c(R).
- Non-thermal support: f_nonth and σ_turb and their coupling to hysteresis amplitude.
Unified Fitting Conventions (Three Axes + Path/Measure Declaration)
- Observable axis: τ_lag, φ_lag, A_hys, |G|, arg(G), ω_c, Δq(R), ΔV_c(R), f_nonth, σ_turb, P(|target−model|>ε).
- Medium axis: Sea / Thread / Density / Tension / Tension Gradient weighting for bar/ring/nuclear gas and hot halo coupling to the dark halo.
- Path & Measure: Angular-momentum/mass fluxes propagate along gamma(ell) with measure d ell; energy/torque accounting uses ∫ J·F dℓ. All formulas are written in backticks; SI units are used.
III. EFT Modeling Mechanisms (Sxx / Pxx)
Minimal Equation Set (plain text)
- S01 τ_lag ≈ τ0 · [1 + a1·γ_Path·J_Path − a2·η_Damp + a3·k_SC·ψ_ring]
- S02 φ_lag(ω) ≈ arctan(ω/ω_c) + b1·k_STG·G_env − b2·θ_Coh
- S03 A_hys ≈ c1·θ_Coh − c2·η_Damp + c3·zeta_topo·Recon(Topology)
- S04 |G|(ω) ≈ G0 / √(1 + (ω/ω_c)^2); ω_c ≈ ω0 · (ξ_RL − η_Damp + θ_Coh)
- S05 Δq(R) ≈ d1·k_STG·Λ_shear + d2·γ_Path·Λ_flow − d3·k_TBN·σ_env
- S06 ΔV_c(R) ≈ e1·k_SC·ψ_bar − e2·β_TPR·ψ_agn + e3·θ_Coh
- S07 J_Path = ∫_gamma (∇μ_E · d ell)/J0
Mechanistic Highlights (Pxx)
- P01 · Path/Sea Coupling. γ_Path×J_Path with k_SC converts bar/ring forcing into delayed halo-potential response, increasing τ_lag and A_hys.
- P02 · STG/TBN. STG shifts phase and shape under shear/tension gradients; TBN sets frequency-response floors and damps Δq ripples.
- P03 · Coherence Window/Response Limit/Damping. Jointly determine ω_c, constraining amplification and preventing non-physical overshoot.
- P04 · TPR/Topology/Recon. β_TPR tunes nuclear-endpoint injection; zeta_topo + Recon modulate loop areas and ΔV_c profiles via bar–ring–halo networks.

VI. Assessment
Strengths
- Unified multiplicative structure (S01–S07) jointly captures time/phase lags, loop areas and frequency knees, halo-shape/rotation corrections, and non-thermal coupling, with interpretable parameters linked directly to bar/ring/nuclear forcing and angular-momentum closure.
- Mechanistic identifiability. Posterior significance of γ_Path/k_SC/k_STG/k_TBN/β_TPR/θ_Coh/η_Damp/ξ_RL/ζ_topo and ψ_bar/ψ_ring/ψ_agn separates path, medium, and topology contributions.
- Operational utility. Enhancing bar–ring–halo connectivity, stabilizing coherence windows, and moderating damping can lower φ_lag and τ_lag, maintain desired ΔV_c, and prevent excessive A_hys energy cycling.
Limitations
- Non-stationary forcing epochs. Bursty AGN/SF introduce fractional-memory and multi-timescale couplings; fractional and time-varying kernels are warranted.
- Geometry/mass-decomposition systematics. Deprojection and M/L assumptions in lensing/rotation fields affect Δq/ΔV_c; multi-method cross-calibration is needed.
Falsification Line & Experimental Suggestions
- Falsification. See the JSON falsification_line.
- Experiments.
- Frequency-response maps: stratify by bar/ring strength to chart |G|(ω), φ_lag(ω) and identify linear vs. saturated regimes of ω_c.
- Loop-area imaging: reconstruct A_hys(R) from mass–potential perturbation curves; test zeta_topo·Recon modulation.
- Non-thermal synergy: concurrent X/SZ and narrow-band fluid diagnostics for f_nonth, σ_turb to constrain the linear contribution of TBN.
- Time-domain blind tests: multi-epoch re-fits of τ_lag, φ_lag to verify stability of θ_Coh ↔ ξ_RL.
