TL;DR: In this article, the effect of grain size distribution on photo-electric heating by grains in photo-ionized regions has been studied, and it has been shown that this effect is nothing short of dramatic.

TL;DR: In this article, the first searches using CMB polarization for correlations induced by a possible non-trivial topology with a fundamental domain that intersects or nearly intersects, the last-scattering surface were performed via a direct scan for matched circular patterns at the intersections and by an optimal likelihood calculation for specific topologies.

TL;DR: In this paper, the authors compare the dust and cosmic rays in the Chamaeleon clouds with the results obtained from the Fermi Large Area Telescope (LAT) and IRAS, and provide average values for the dust properties per gas nucleon in different phases.

TL;DR: In this article, the main aspects of the Planck optics that are relevant to science, and the estimated in-flight performance, based on the knowledge available at the time of launch, are described.

TL;DR: In this article, the authors measured the sub-millimetre polarized intensity and the optical depth in the V band to the star in the Planck 353 GHz channel, and derived the degree of polarization and optical depth.
