TL;DR: In this paper, a large-scale view of the Planck HFI at 353 GHz is presented, showing that the maximum observed dust polarization fraction is high in some of the intermediate dust column density (AV < 1mag) regions.

TL;DR: In this article, the authors presented an overview of the polarized sky as seen by Planck HFI at 353 GHz, which is the most sensitive Planck channel for dust polarization.

TL;DR: In this paper, the authors used simulations of anisotropic magnetohydrodynamical turbulence in which they assume a uniform intrinsic polarization fraction of the dust grains and found that an estimate of this parameter may be recovered from the maximum polarization fraction pmax in diffuse regions where the magnetic field is ordered on large scales and perpendicular to the line of sight.

TL;DR: In this article, the authors employed the NARVAL and ESPaDOnS high-resolution spectropolarimeters to collect 442 circularly polarized spectra, complemented by 60 linearly polarized spectras, and computed a cross correlation line profile from every spectrum, leading to a signal-to-noise ratio of up to 30'000 in the polarized profile.

TL;DR: In this article, the authors used ancillary catalogues of the Planck survey to obtain the degree of polarization, pV, and optical depth in the V band to the star τV.
