A new approach for the statistical denoising of Planck interstellar dust polarization data
Bruno Regaldo-Saint Blancard, Erwan Allys, François Boulanger +2
Dust emission is the main foreground for cosmic microwave background (CMB) polarization. Its statistical characterization must be derived from the analysis of observational data be…
Statistical description of dust polarized emission from the diffuse interstellar medium -- A RWST approach
