Journal ArticleDOI

Planck 2013 results. XII. Diffuse component separation

Peter A. R. Ade, +321 more
TL;DR: In this article, the authors presented full-sky maps of the cosmic microwave background (CMB) and polarized synchrotron and thermal dust emission, derived from the third set of Planck frequency maps.
Journal ArticleDOI

Planck 2013 results. XII. Component separation

P. A. R. Ade, +259 more
TL;DR: In this article, the authors describe the component separation framework adopted by Planck and test four foreground-cleaned CMB maps derived using qualitatively different component separation algorithms, and show that these maps are internally consistent and robust for CMB power spectrum and cosmological parameter estimation up to l = 2000.
Journal ArticleDOI

Planck Early Results. VII. The Early Release Compact Source Catalog

P. A. R. Ade, +229 more
TL;DR: The Planck Early Release Compact Source Catalogue (ERCSC) as discussed by the authors is a large-scale source catalog that contains more than 15,000 unique sources with known associations to stars with dust shells, stellar cores, radio galaxies, blazars, infrared luminous galaxies and Galactic interstellar medium features.
Journal ArticleDOI

Planck 2013 results. XXX. Cosmic infrared background measurements and implications for star formation

Peter A. R. Ade, +306 more
TL;DR: In this article, the authors present new measurements of cosmic infrared background (CIB) anisotropies using Planck, which are used to understand the process of galaxy formation.
Journal ArticleDOI

Planck 2013 results. XXV. Searches for cosmic strings and other topological defects

Peter A. R. Ade, +226 more
TL;DR: In this paper, the angular power spectrum from strings has been used to provide stringent new constraints on cosmic strings and other defects, such as the string tension, which can be improved to 1.015 at 95% confidence with the inclusion of high-ell$ CMB data.
