First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Tests of Gaussianity
E. Komatsu, A. Kogut, M. Nolta +12
We present limits to the amplitude of non-Gaussian primordial fluctuations in the WMAP 1-year cosmic microwave background sky maps. A non-linear coupling parameter, f_NL, character…
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Beam Profiles and Window Functions
L. Page, C. Barnes, G. Hinshaw +11
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 i…
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Determination of Cosmological Parameters
D. N. Spergel, L. Verde, H. V. Peiris +14
WMAP precision data enables accurate testing of cosmological models. We find that the emerging standard model of cosmology, a flat Lambda-dominated universe seeded by nearly scale-…
The Optical Design and Characterization of the Microwave Anisotropy Probe
L. Page, C. Jackson, C. Barnes +12
The primary goal of the MAP satellite, now in orbit, is to make high fidelity polarization sensitive maps of the full sky in five frequency bands between 20 and 100 GHz. From these…
