Constraining the Topology of the Universe
Neil J. Cornish, David N. Spergel, Glenn D. Starkman +1
The first year data from the Wilkinson Microwave Anisotropy Probe are used to place stringent constraints on the topology of the Universe. We search for pairs of circles on the sky…
Measuring primordial non-Gaussianity in the cosmic microwave background
Eiichiro Komatsu, David N. Spergel, Benjamin D. Wandelt
We derive a fast way for measuring primordial non-Gaussianity in a nearly full-sky map of the cosmic microwave background. We find a cubic combination of sky maps combining bispect…
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Angular Power Spectrum
G. Hinshaw, D. N. Spergel, L. Verde +14
We present the angular power spectrum derived from the first-year Wilkinson Microwave Anisotropy Probe (WMAP) sky maps. We study a variety of power spectrum estimation methods and…
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: 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-…
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Preliminary Maps and Basic Results
C. L. Bennett, M. Halpern, G. Hinshaw +18
We present full sky microwave maps in five bands (23 to 94 GHz) from the WMAP first year sky survey. Calibration errors are <0.5% and the low systematic error level is well specifi…
