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 authors used a combination of the orbital dipole plus the solar dipole to estimate the signal generated by the dipole in the CMB rest frame of the Planck spacecraft.

TL;DR: In this paper, a fully covariant and gauge-invariant calculation of the evolution of anisotropies in the cosmic microwave background (CMB) radiation has been presented.

TL;DR: In this paper, the beam normalization and beam window functions for the Planck Low Frequency Instrument (LFI) were characterized and the uncertainties in the beam window function were analyzed.

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.
