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.

TL;DR: The first searches using CMB polarization for correlations induced by a non-trivial topology with a fundamental domain intersecting or nearly intersecting, the last scattering surface (at comoving distance) were performed by as discussed by the authors.

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 article, the spectral energy distributions (SEDs) of distant sub-millimetre (submm) galaxies are measured using parametric models to determine the range of dust temperatures and emissivities, and the results show that cold (T < 20 K) dust is a significant and largely unexplored component of many nearby galaxies.

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.
