First year Wilkinson Microwave Anisotropy Probe (WMAP) observations: Determination of cosmological parameters
- D. Spergel, L. Verde, +20 authors Ucla
- Physics
- 11 February 2003
WMAP precision data enable accurate testing of cosmological models. We find that the emerging standard model of cosmology, a flat � -dominated universe seeded by a nearly scale-invariant adiabatic… Expand

FIRST-YEAR WILKINSON MICROWAVE ANISOTROPY PROBE (WMAP) 1 OBSERVATIONS: TEMPERATURE-POLARIZATION CORRELATION
The Wilkinson Microwave Anisotropy Probe (WMAP) has mapped the full sky in Stokes I, Q, and U parameters at frequencies of 23, 33, 41, 61, and 94 GHz. We detect correlations between the temperature… Expand
First-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Parameter Estimation Methodology
We describe our methodology for comparing the Wilkinson Microwave Anisotropy Probe (WMAP) measurements of the cosmic microwave background (CMB) and other complementary data sets to theoretical… Expand
The Cluster mission

- Geography
- 1 December 2001
The Cluster mission, ESA's first cornerstone project, together with the SOHO mission, dating back to the first proposals in 1982, was finally launched in the summer of 2000. On 16 July and 9 August,… Expand

First-year Wilkinson Microwave Anisotropy Probe (WMAP) observations: Tests of Gaussianity
- E. Komatsu, A. Kogut, +17 authors Ucla
- Physics
- 11 February 2003
We present limits to the amplitude of non-Gaussian primordial fluctuations in the WMAP 1 yr cosmic microwave background sky maps. A nonlinear coupling parameter, fNL, characterizes the amplitude of a… Expand
Seven-year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Planets and Celestial Calibration Sources
- J. Weiland, N. Odegard, +29 authors Ucla
- Physics
- 26 January 2010
We present WMAP seven-year observations of bright sources which are often used as calibrators at microwave frequencies. Ten objects are studied in five frequency bands (23-94 GHz): the outer planets… Expand
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Beam Profiles and Window Functions
Knowledge of the beam profiles is of critical importance for interpreting data from cosmic microwave background experiments. In this paper, we present the characterization of the in-flight optical… Expand
Intermediate-Element Abundances in Galaxy Clusters
- W. Baumgartner, D. Horner, Richard F. Mushotzky University of Maryland, Nasa Gsfc, Stsci
- Physics
- 9 July 2002
We present the average abundances of the intermediate elements obtained by performing a stacked analysis of all the galaxy clusters in the archive of the X-ray telescope ASCA. We determine the… Expand
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Interpretation of the TT and TE Angular Power Spectrum Peaks
The CMB has distinct peaks in both its temperature angular power spectrum (TT) and temperature-polarization cross-power spectrum (TE). From the WMAP data we find the first peak in the temperature… Expand
