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.

TL;DR: In this paper, the authors used observations of the nearby Chamaeleon clouds in gamma rays with the Fermi Large Area Telescope and in thermal dust emission with Planck and IRAS to map the gas column densities in different phases and at the dark neutral medium (DNM) transition between the HI-bright and CO-bright media; constrain the CO-to-H_2$ conversion factor, $X_{CO}$; and probe the dust properties per gas nucleon in each gas phase and spatially across the clouds.

TL;DR: In this article, the fraction of cool-core clusters in the early Sunyaev-Zel'dovich sample of 164 clusters with $z ≤ 0.35$ and in a flux-limited X-ray sample of 100 clusters with

TL;DR: In this article, the authors present further results from the ongoing XMM-Newton validation follow-up of Planck cluster candidates, detailing X-ray observations of eleven candidates detected at a signal-to-noise ratio of 4.5 < S/N < 5.3 in the same 10-month survey maps used in the construction of the Early SZ sample.

TL;DR: The first results on PLCK G266.3, a galaxy cluster candidate detected at a signal-to-noise ratio of 5 in the Planck All Sky survey, were presented in this article.
