MSFCM Paper VIII: Cross-Correlation of the LoTSS DR2 Jet–Filament Anisotropy Tensor Q22 with the Planck SMICA CMB Temperature Power Spectrum — A Null Result Consistent with ΛCDM and Constraints on the SGCC Spin-Memory Hypothesis
Year: 2026
Type: preprint
Abstract: Paper VIII of the MSFCM series. We cross-correlate the projected Q22 jet–filament anisotropy tensor (LoTSS DR2, N=120,331 AGN–filament pairs) with the Planck SMICA CMB temperature map using the MASTER pseudo-Cl estimator (NaMaster). Result: chi2=0.01, dof=9, sigma=0.0 in the signal window 20≤ℓ≤150, fully consistent with ΛCDM null hypothesis. fsky=0.11, Nside=64, Δℓ=15. Rules out primordial CMB origin for the SGCC alignment effect. Pipeline: NaMaster v2.6, healpy, WSL2 Ubuntu.
