TL;DR: In this paper, the authors used the temperature-gradient correlations induced by lensing to reconstruct a (noisy) map of the CMB lensing potential, which provides an integrated measure of the mass distribution back to the last-scattering surface.

TL;DR: In this paper, an elliptical shape having semi-major axes of 100 and 60 pc is deduced, and the major axis of this 100 pc ring is inclined by about 40 degrees with respect to the plane of sky and is oriented perpendicular to the major axes of the Galactic Bar.

TL;DR: In this paper, the relative orientation between the magnetic field projected on the plane of sky, inferred from the polarized thermal emission of Galactic dust observed by Planck at 353 GHz, and the gas column density structures, quantified by the gradient of the column density, was evaluated pixel by pixel and analysed in bins of column density using the novel statistical tool called "histogram of relative orientations".

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: The ESA's Planck satellite was launched 14 May 2009 and has been scanning the microwave and sub-millimetre sky continuously since 12 August 2009 as discussed by the authors, where it has measured gravitational lensing of CMB anisotropies at greater than 25 sigma.
