This paper presents the large-scale polarized sky as seen by Planck HFI at 353 GHz, which is the most sensitive Planck channel for dust polarization.  ...  There is a systematic decrease in the dust polarization fraction with increasing dust column density, and we interpret the features of this correlation in light of both radiative grain alignment predictions  ...  Such a decrease of the polarization fraction toward large column densities on small (∼a few 0.1 pc) scales was reported previously in ground-based measurements of polarization both in emission (Ward-Thompson  ...
