Journal ArticleDOI

Planck 2013 results. I. Overview of products and scientific results

Peter A. R. Ade, +472 more
TL;DR: The European Space Agency's Planck satellite, dedicated to studying the early Universe and its subsequent evolution, was launched 14 May 2009 and has been scanning the microwave and submillimetre sky continuously since 12 August 2009 as discussed by the authors.
Journal ArticleDOI

Planck 2013 results. XV. CMB power spectra and likelihood

Peter A. R. Ade, +258 more
TL;DR: In this article, the Planck likelihood is used to derive the CMB power spectrum over three decades in l, covering 2 = 50, and employ a correlated Gaussian likelihood approximation based on angular cross-spectra derived from the 100, 143 and 217 GHz channels.
Journal ArticleDOI

Planck 2013 results. XV. CMB power spectra and likelihood

Peter A. R. Ade, +328 more
TL;DR: The Planck 2013 likelihood as mentioned in this paper is a complete statistical description of the two-point correlation function of the CMB temperature fluctuations that accounts for all known relevant uncertainties, both instrumental and astrophysical in nature.
Journal ArticleDOI

Planck 2013 results. I. Overview of products and scientific results

Peter A. R. Ade, +470 more
TL;DR: The ESA's Planck satellite was launched 14 May 2009 and has been scanning the microwave and sub-millimetre sky continuously since 12 August 2009 as discussed by the authors, where it has measured gravitational lensing of CMB anisotropies at greater than 25 sigma.
Journal ArticleDOI

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

Peter A. R. Ade, +287 more
TL;DR: In this article, 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.
