Seven-year wilkinson microwave anisotropy probe (wmap *) observations: cosmological interpretation
Eiichiro Komatsu,Kristine M. Smith,Jo Dunkley,Charles L. Bennett,B. Gold,Gary Hinshaw,Norman Jarosik,Davin Larson,M. R. Nolta,Lyman A. Page,David N. Spergel,Mark Halpern,Robert S. Hill,A. Kogut,Michele Limon,S. S. Meyer,N. Odegard,Gregory S. Tucker,Janet Weiland,Edward J. Wollack,Edward L. Wright +20 more
TL;DR: In this article, a combination of seven-year data from WMAP and improved astrophysical data rigorously tests the standard cosmological model and places new constraints on its basic parameters and extensions.
Journal ArticleDOI

Kogut,Michele Limon,S. S. Meyer,N. Odegard,G. S. Tucker,Janet Weiland,Edward J. Wollack,Edward L. Wright +21 more
TL;DR: In this article, a simple cosmological model with only six parameters (matter density, Omega_m h^2, baryon density, BH 2, Hubble Constant, H_0, amplitude of fluctuations, sigma_8, optical depth, tau, and a slope for the scalar perturbation spectrum, n_s) was proposed to fit the three-year WMAP temperature and polarization data.

Five-year wilkinson microwave anisotropy probe observations: cosmological interpretation
Eiichiro Komatsu,Jo Dunkley,Jo Dunkley,M. R. Nolta,Charles L. Bennett,B. Gold,Gary Hinshaw,N. Jarosik,Davin Larson,Michele Limon,Lyman A. Page,David N. Spergel,Mark Halpern,Robert S. Hill,Alan J. Kogut,S. S. Meyer,Gregory S. Tucker,Janet Weiland,Edward J. Wollack,Edward L. Wright +19 more
TL;DR: In this article, the Wilkinson Microwave Anisotropy Probe (WMAP) 5-year data were used to constrain the physics of cosmic inflation via Gaussianity, adiabaticity, the power spectrum of primordial fluctuations, gravitational waves, and spatial curvature.

Five-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Cosmological Interpretation
Eiichiro Komatsu,Jo Dunkley,M. R. Nolta,Charles L. Bennett,B. Gold,Gary Hinshaw,Norman Jarosik,David L. Larson,Michele Limon,L. Page,David N. Spergel,Mark Halpern,Robert S. Hill,A. Kogut,S. S. Meyer,G. S. Tucker,Janet Weiland,Edward J. Wollack,Edward L. Wright +18 more
TL;DR: In this paper, the authors show that the tensor-to-scalar ratio r 1 is disfavored regardless of r. They provide a set of "WMAP distance priors, to test a variety of dark energy models.

TL;DR: In this paper, the authors present full sky microwave maps in five frequency bands (23 to 94 GHz) from the WMAP first year sky survey, which are consistent with the 7 in. full-width at half-maximum (FWHM) Cosmic Background Explorer (COBE) maps.
