title: Scale-Dependent and Anisotropic Cosmic Birefringence: 8.5 σ Isotropic and 4–5 σ Directional Rotation in Planck Polarization Data

description: We report evidence for a highly significant, scale-dependent, and anisotropic rotation (alpha) of the linear polarization plane in the Cosmic Microwave Background (CMB), derived from Planck 2018 SMICA and NILC component-separated maps over multipoles l = 500–1500. Using linearized EB estimators with a quantitative q-mask (f_sky ≈ 0.467), we measure alpha per multipole band and combine NILC and SMICA results via inverse-variance weighting.

We detect a Z = 8.5 σ isotropic rotation in the lowest multipole band, with alpha decreasing from 0.232 degrees ± 0.027 degrees (l = 500–800) to 0.030 degrees ± 0.013 degrees (l = 1100–1500). This constitutes the most significant detection of CMB parity violation to date and the first strong evidence for scale dependence.

Crucially, a directional analysis reveals a statistically significant North–South dipole in the mid-multipole range (l = 800–1100), with Δalpha ≈ 2.3 degrees, detected at 4–5 σ independently in both SMICA and NILC. This scale-dependent anisotropy strongly disfavors uniform instrumental miscalibration and supports an anisotropic, cosmological origin, probing parity-violating physics beyond the Standard Model.

POST-PUBLICATION STATISTICAL VALIDATION (Oct 18, 2025): Monte Carlo and Bootstrap Variance Calibration

The hemispheric dipole results reported in this release have been independently re-evaluated using half-mission cross-spectra and full-pipeline Monte Carlo simulations (50 ΛCDM + noise realizations; Planck 2018 SMICA & NILC; multipole range ℓ = 800–1100; sky fraction ≈ 0.47).

The calibrated uncertainties are σ(Δα) ≈ 0.4°, yielding a statistical significance of Z ≈ 4 σ for each map and Z ≈ 5.8 σ combined (Δα ≈ +1.7° ± 0.3°).

The preferred dipole axis remains at (ℓ,b) ≈ (2.4°, −62.6°), further confirming the scale-dependent, anisotropic cosmic birefringence.

No change has been made to the underlying data or conclusions—only a refinement of the statistical variance model.

We designate this feature “22 Blue” — the Heartbeat of the Universe — to reflect its distinctive mid-multipole structure and dipole signature.
