Journal ArticleDOI
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
First year Wilkinson Microwave Anisotropy Probe (WMAP) observations: Determination of cosmological parameters
David N. Spergel,Licia Verde,Hiranya V. Peiris,Eiichiro Komatsu,M. R. Nolta,Charles L. Bennett,Mark Halpern,Gary Hinshaw,N. Jarosik,Alan J. Kogut,Michele Limon,Michele Limon,S. S. Meyer,Lyman A. Page,Gregory S. Tucker,Gregory S. Tucker,Gregory S. Tucker,Janet L. Weiland,Edward J. Wollack,Edward L. Wright +19 more
TL;DR: In this article, the authors find that the emerging standard model of cosmology, a flat -dominated universe seeded by a nearly scale-invariant adiabatic Gaussian fluctuations, fits the WMAP data.
Journal ArticleDOI
Wilkinson Microwave Anisotropy Probe (WMAP) Three Year Results: Implications for Cosmology

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.
Journal ArticleDOI
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.
