Statistical signatures of interstellar turbulence in dust polarization maps

Astrophysics of Galaxies 2025-11-11 v2 Cosmology and Nongalactic Astrophysics

Abstract

We present results from a high-resolution interstellar turbulence simulation and show that it closely reproduces recent PlanckPlanck measurements. Our model captures the scaling of EEEE and BBBB spectra, and the EE/BBEE/BB ratio in the inertial range. The probability density function of the dust polarization fraction is also consistent with observations. The TETE cross-correlation is in broad agreement with the PlanckPlanck sky. This simulation provides new insights into the physical origins of the observed E/BE/B asymmetry and positive TETE signal, facilitating the development of advanced Galactic dust emission models for current and future cosmic microwave background experiments.
