Journal ArticleDOI

Planck 2015 results. XVIII. Background geometry & topology

P. A. R. Ade, +224 more
TL;DR: The first searches using CMB polarization for correlations induced by a non-trivial topology with a fundamental domain intersecting or nearly intersecting, the last scattering surface (at comoving distance) were performed by as discussed by the authors.
Journal ArticleDOI

Planck 2013 results - XXVI. Background geometry and topology of the Universe

Peter A. R. Ade, +269 more
TL;DR: In this article, the first searches using CMB polarization for correlations induced by a possible non-trivial topology with a fundamental domain that intersects or nearly intersects, the last-scattering surface were performed via a direct scan for matched circular patterns at the intersections and by an optimal likelihood calculation for specific topologies.
Journal ArticleDOI

Planck early results. XVI. The Planck view of nearby galaxies

Peter A. R. Ade, +232 more
TL;DR: In this article, the spectral energy distributions (SEDs) of distant sub-millimetre (submm) galaxies are measured using parametric models to determine the range of dust temperatures and emissivities, and the results show that cold (T < 20 K) dust is a significant and largely unexplored component of many nearby galaxies.
Journal ArticleDOI

Planck intermediate results - XXVIII. Interstellar gas and dust in the Chamaeleon clouds as seen by Fermi LAT and Planck

Peter A. R. Ade, +225 more
TL;DR: In this paper, the authors compare the dust and cosmic rays in the Chamaeleon clouds with the results obtained from the Fermi Large Area Telescope (LAT) and IRAS, and provide average values for the dust properties per gas nucleon in different phases.
Journal ArticleDOI

Planck intermediate results - XIII. Constraints on peculiar velocities

Peter A. R. Ade, +228 more
TL;DR: In this article, the authors used Planck data combined with the Meta Catalogue of X-ray detected Clusters of galaxies (MCXC) to address the study of peculiar motions by searching for evidence of the kinetic Sunyaev-Zeldovich effect (kSZ).
