Hemispherical Power Asymmetry in the Three-year Wilkinson Microwave Anisotropy Probe Sky Maps
We consider the issue of hemispherical power asymmetry in the three-year WMAP data, adopting a previously introduced modulation framework. Computing both frequentist probabilities and Bayesian evidences, we find that the model consisiting of an isotropic CMB sky modulated by a dipole field, gives a substantially better fit to the observations than the purely isotropic model, even when accountin...
متن کاملThe N -point Correlation Functions of the First-year Wilkinson Microwave Anisotropy Probe Sky Maps
We compute the two-, threeand four-point correlation functions from the Wilkinson Microwave Anisotropy Probe (WMAP) data, and compare these to a Monte Carlo ensemble of 5000 realizations, based on the best-fit WMAP running-index spectrum of Gaussian fluctuations. The analysis is carried out in three steps, covering small (< 72), intermediate (< 5) and large scales (up to 180). On the largest sc...
متن کاملFive - Year Wilkinson Microwave Anisotropy Probe ( WMAP 1 ) Observations : Data Processing , Sky Maps , & Basic Results
We present new full-sky temperature and polarization maps in five frequency bands from 23 to 94 GHz, based on data from the first five years of the WMAP sky survey. The new maps are consistent with previous maps and are more sensitive. The five-year maps incorporate several improvements in data processing made possible by the additional years of data and by a more complete analysis of the instr...

متن کاملSeven-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Sky Maps, Systematic Errors, and Basic Results
New full sky temperature and polarization maps based on seven years of data from WMAP are presented. The new results are consistent with previous results, but have improved due to reduced noise from the additional integration time, improved knowledge of the instrument performance, and improved data analysis procedures. The improvements are described in detail. WMAP is the result of a partnershi...
