TL;DR: An excess of B-mode power over the base lensed-ΛCDM expectation is found in the range 30 < ℓ < 150, inconsistent with the null hypothesis at a significance of >5σ, and it is shown that systematic contamination is much smaller than the observed excess.

TL;DR: The Wilkinson Microwave Anisotropy Probe (WMAP) is a medium-class Explorer (MIDEX) satellite aimed at elucidating cosmology through full-sky observations of the cosmic microwave background (CMB) as mentioned in this paper.

TL;DR: In this article, a simple LCDM cosmological model was used to fit the five-year WMAP temperature and polarization data, and the upper bound on the tensor-to-scalar ratio was improved to r < 0.43.

TL;DR: In this paper, the first five years of the WMAP sky survey were used for full-sky temperature and polarization maps in five frequency bands from 23 to 94 GHz, and several new tests for systematic errors in the polarization data and conclude that Ka band data (33 GHz) is suitable for use in cosmological analysis, after foreground cleaning.

TL;DR: In this paper, the authors present cosmological constraints from the Wilkinson Microwave Anisotropy Probe (WMAP) alone for both the ACDM model and a set of possible extensions.
