摘要：Galactic dust is known to cosmologists as the dominant foreground to CMB measurements above » 100 GHz, especially when dealing with polarization. In this paper, we summarize how the size of dust grains affects their alignment properties and therefore both the optical polarization and the polarization of their radiation. We compare theoretical expectations and experimental measurements. At the present time there is a lack of precise experimental information to predict to what level exactly dust can be removed from CMB data in our quest for the primordial B modes.
