Magnetic Misalignment of Interstellar Dust Filaments

Understand

We present evidence for scale-independent misalignment of interstellar dust filaments and magnetic fields.

• We estimate the misalignment by comparing millimeter-wave dust-polarization measurements from Planck with filamentary structures identified in neutral-hydrogen (HI) measurements from HI4PI.
• We find that the misalignment angle displays a scale independence (harmonic coherence) for features larger than the HI4PI beam width ($16.2'$).
• We additionally find a spatial coherence on angular scales of $\mathcal{O}(1^\circ)$.
