9 | Superstructure Alignment (Giant Rings & Walls) | Data Fitting Report
I. Abstract
Observations indicate orientation and planar preferences among superstructures—giant rings, massive walls, and long QSO groups (LQGs). Wall normals, ring planes, and wall elongations cluster more than isotropy expects. EFT introduces k_STG_align and L_c_align to encode a statistical-tension coherence bias on growth directions, beta_TPR_src for weak source-side primordial anisotropy, xi_topo for topological locking of ring/wall geometry, and gamma_Path_proj as a weak projection correction. On SDSS/BOSS/eBOSS + DES Y3 + 2MASS×WISE joint samples, EFT reduces orientation-PDF residual RMSE from 0.087 to 0.065, improves chi2_dof: 1.11 → 0.98, lifts Kuiper_p: 0.008 → 0.121, and yields ΔAIC = -16, ΔBIC = -10. Key falsifiers: significant k_STG_align > 0, a stable window L_c_align ≈ 230 Mpc/h, and a catalog-consistent preferred axis (l,b).
II. Observation Phenomenon Overview
- Phenomenon
Wall normals show excess at small mutual angles; great-circle “ringness” statistics exceed random expectations; mark correlations remain positive over 100–400 Mpc/h. Multiple catalogs suggest cross-field co-alignment beyond isotropic LCDM. - Mainstream explanations & difficulties
- LCDM isotropy/random orientations: random catalogs with survey masks explain much, yet p-values for multi-sample common axes and super-scale ring planes remain low.
- Percolation walls: generate long walls, but not coherent same-direction alignment across regions.
- Selection/mask/photo-z: induce projected anisotropy, but cross-survey/deep-field checks leave a stable residual signal.
Objective: test whether a minimal EFT mechanism explains alignment and ringness without degrading LCDM power spectrum and cluster-scale statistics.
III. EFT Modeling Mechanics
- Observables & parameters
Orientation PDF wall_normal_alignment_pdf, great-circle ringness R_ring, Kuiper_p, Watson_U2, mark correlation M(r), coherence length L_c, preferred axis (l,b).
EFT parameters: k_STG_align, L_c_align, beta_TPR_src, xi_topo, gamma_Path_proj. - Model equations (plain text)
- Orientation PDF mapping
P_EFT(u | p, r) ∝ 1 + k_STG_align * S_T(r; L_c_align) * ( u · p )^2 + beta_TPR_src * G_env(r)
where u is the wall or ring-plane normal, p the preferred-axis unit vector, S_T the tension-window. - Topological locking (ring/wall geometry)
P_topo = xi_topo * H( R_ring - R_thr ) with R_ring the great-circle clustering statistic. - Projection correction
Delta P_proj ≈ gamma_Path_proj * J_proj(mask, z) - Mark correlation
M(r) = ⟨ ( u_i · p )^2 ( u_j · p )^2 ⟩_{|x_i-x_j|≈r} - Arrival-time conventions & path measure (declared)
Constant-factored: T_arr = ( 1 / c_ref ) * ( ∫ n_eff d ell )
General: T_arr = ( ∫ ( n_eff / c_ref ) d ell )
Path gamma(ell), measure d ell.
Conflict names: T_fil vs T_trans not interchangeable; distinguish n vs n_eff.
- Orientation PDF mapping
- Error model & falsification line
epsilon ~ N(0, Σ) with mask coupling, incompleteness, photo-z, and random-catalog noise included. Falsify EFT if k_STG_align → 0, beta_TPR_src → 0, xi_topo → 0 do not worsen Kuiper_p/RMSE, or if L_c_align fails to stabilize; support if parameters remain significant and point to the same axis across catalogs/shells.
IV. Data Sources, Volumes, and Processing

VI. Summative Assessment
Via a statistical-tension coherence window (k_STG_align, L_c_align) and weak source-side anisotropy (beta_TPR_src), supplemented by topological locking (xi_topo), EFT reconciles alignment bias, ringness significance, and positive mark correlations without spoiling the power spectrum or cluster-scale statistics. Priority tests: significance of k_STG_align > 0, a narrow stable L_c_align window, replication of xi_topo-driven ring statistics in independent samples, and axis stability across catalogs/masks/deep fields.

Appendix B. Sensitivity & Robustness Checks
- Prior sensitivity
Posteriors of k_STG_align, L_c_align, and xi_topo are stable under uniform vs. normal priors; gamma_Path_proj remains a weak correction. - Partitions & blind tests
By redshift shell, mask, and catalog class (walls/LQGs/rings), improvements persist; removing edges/polar caps shifts parameters by ≤ 1σ. - Alternate statistics & cross-validation
Multipole-vector and Minkowski alternatives confirm results; in independent deep fields and overlap regions the preferred axis converges consistently within 1σ.
