Lyman A. Page,Gary Hinshaw,Eiichiro Komatsu,Michael R. Nolta,David N. Spergel,Charles L. Bennett,Cris W. Barnes,Rachel Bean,Rachel Bean,Olivier Doré,Olivier Doré,Jo Dunkley,Mark Halpern,Robert S. Hill,N. Jarosik,Alan J. Kogut,Michele Limon,S. S. Meyer,N. Odegard,Hiranya V. Peiris,Gregory S. Tucker,Licia Verde,Janet L. Weiland,Edward J. Wollack,Edward L. Wright +24 more
TL;DR: In this article, the authors presented a model of polarized foreground emission that captures the large angular scale characteristics of the microwave sky and analyzed the 3-year full-sky maps of the polarization and cosmological implications.

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.

Five-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Likelihoods and Parameters from the WMAP data

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.

Gary Hinshaw,Janet Weiland,Robert S. Hill,N. Odegard,David L. Larson,Charles L. Bennett,Jo Dunkley,B. Gold,M. R. Greason,Norman Jarosik,Eiichiro Komatsu,M. R. Nolta,L. A. Page,David N. Spergel,Edward J. Wollack,Mark Halpern,A. Kogut,Michele Limon,S. S. Meyer,G. S. Tucker,Edward L. Wright +20 more
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.
