The Hot and Cold Spots in Five-Year WMAP Data
Zhen Hou, A. J. Banday, K. M. Gorski
We present an extensive frequentist analysis of the one-point statistics (number, mean, variance, skewness and kurtosis) and two-point correlation functions determined for the loca…
The Origin of the Universe as Revealed Through the Polarization of the Cosmic Microwave Background
S. Dodelson, R. Easther, S. Hanany +61
Modern cosmology has sharpened questions posed for millennia about the origin of our cosmic habitat. The age-old questions have been transformed into two pressing issues primed for…
A model-independent test for scale-dependent non-Gaussianities in the CMB
C. Raeth, G. Morfill, G. Rossmanith +2
We present a model-independent method to test for scale-dependent non-Gaussianities in combination with scaling indices as test statistics. Therefore, surrogate data sets are gener…
The scalar perturbation spectral index n_s: WMAP sensitivity to unresolved point sources
K. M. Huffenberger, H. K. Eriksen, F. K. Hansen +2
Precision measurement of the scalar perturbation spectral index, n_s, from the Wilkinson Microwave Anisotropy Probe temperature angular power spectrum requires the subtraction of u…
Hemispherical power asymmetry in the three-year Wilkinson Microwave Anisotropy Probe sky maps
H. K. Eriksen, A. J. Banday, K. M. Gorski +2
We consider the issue of hemispherical power asymmetry in the three-year WMAP data, adopting a previously introduced modulation framework. Computing both frequentist probabilities…
Bayesian foreground analysis with CMB data
H. K. Eriksen, C. Dickinson, C. R. Lawrence +6
The quality of CMB observations has improved dramatically in the last few years, and will continue to do so in the coming decade. Over a wide range of angular scales, the uncertain…
