Continuum spectra covering centimetre to submillimetre wavelengths are presented for a northern sample of 104 extragalactic radio sources, mainly active galactic nuclei, based on f…
Planck intermediate results. XLIV. The structure of the Galactic magnetic field from dust polarization maps of the southern Galactic cap
Planck Collaboration, N. Aghanim, M. I. R. Alves +165
We study the statistical properties of interstellar dust polarization at high Galactic latitude, using the Stokes parameter Planck maps at 353 GHz. Our aim is to advance the unders…

Planck Collaboration, P. A. R. Ade, N. Aghanim +238
(abridged) We discuss the Galactic foreground emission between 20 and 100GHz based on observations by Planck/WMAP. The Commander component-separation tool has been used to separate…
Planck 2015 results. XXVIII. The Planck Catalogue of Galactic Cold Clumps
Planck Collaboration, P. A. R. Ade, N. Aghanim +220
We present the Planck Catalogue of Galactic Cold Clumps (PGCC), an all-sky catalogue of Galactic cold clump candidates detected by Planck. This catalogue is the full version of the…
Planck intermediate results. XXXV. Probing the role of the magnetic field in the formation of structure in molecular clouds
Planck Collaboration, P. A. R. Ade, N. Aghanim +195
Within ten nearby (d < 450 pc) Gould Belt molecular clouds we evaluate statistically the relative orientation between the magnetic field projected on the plane of sky, inferred fro…
Planck intermediate results. XXXIV. The magnetic field structure in the Rosette Nebula
Planck Collaboration, N. Aghanim, M. I. R. Alves +197
Planck has mapped the polarized dust emission over the whole sky, making it possible to trace the Galactic magnetic field structure that pervades the interstellar medium (ISM). We…
Planck intermediate results. XXXII. The relative orientation between the magnetic field and structures traced by interstellar dust
Planck Collaboration, R. Adam, P. A. R. Ade +199
The role of the magnetic field in the formation of the filamentary structures observed in the interstellar medium (ISM) is a debated topic. The Planck all-sky maps of linearly pola…
Planck intermediate results. XXV. The Andromeda Galaxy as seen by Planck
Planck Collaboration, P. A. R. Ade, N. Aghanim +202
The Andromeda Galaxy (M31) is one of a few galaxies that has sufficient angular size on the sky to be resolved by the Planck satellite. Planck has detected M31 in all of its freque…
Planck intermediate results. XXIII. Galactic plane emission components derived from Planck with ancillary data
Planck Collaboration, P. A. R. Ade, N. Aghanim +189
Planck data when combined with ancillary data provide a unique opportunity to separate the diffuse emission components of the inner Galaxy. The purpose of the paper is to elucidate…
Planck intermediate results. XVII. Emission of dust in the diffuse interstellar medium from the far-infrared to microwave frequencies
Planck Collaboration, A. Abergel, P. A. R. Ade +196
The dust-HI correlation is used to characterize the emission properties of dust in the diffuse interstellar medium. We cross-correlate sky maps from Planck, WMAP, and DIRBE, at 17…
Planck 2013 results. XI. All-sky model of thermal dust emission
Planck Collaboration, A. Abergel, P. A. R. Ade +244
This paper presents an all-sky model of dust emission from the Planck 857, 545 and 353 GHz, and IRAS 100 micron data. Using a modified black-body fit to the data we present all-sky…
