TL;DR: In this paper, a series of ground-based tests were conducted with the HFI focal plane in a cryogenic environment prior to launch to measure the relative spectral response of all HFI detectors to a known source of electromagnetic radiation individually.

TL;DR: The Planck Catalogue of Compact Sources (PCCS) as mentioned in this paper is the catalogue of sources detected in the first 15 months of Planck operations, the "nominal" mission, which consists of nine single-frequency catalogues of compact sources, both Galactic and extragalactic, detected over the entire sky.

TL;DR: In this article, the authors used the generalized needlet internal linear combination (GNILC) method, which uses spatial information (the angular powerspectra) to disentangle the Galactic thermal dust emission and CIB anisotropies.

TL;DR: In this article, the authors discuss the Galactic foreground emission between 20 and 100 GHz based on observations by Planck and WMAP, and identify a number of new faint features in the polarized sky, including a dearth of polarized synchrotron emission directly correlated with a narrow, roughly 20deg long filament seen in Hα at high latitude.

TL;DR: In this article, the authors present a general methodology to study the dust-Hi correlation over the sky, including simulations to quantify uncertainties, and identify a Galactic contribution to these residuals with variations of the dust emissivity on angular scales smaller than that of their correlation analysis.
