Scale-dependent non-Gaussianities in the WMAP data as identified by using surrogates and scaling indices
C. Raeth, A. J. Banday, G. Rossmanith +5
We present a model-independent investigation of the WMAP data with respect to scale- dependent non-Gaussianities (NGs) by employing the method of constrained randomization. For gen…
Measuring Planck beams with planets
K. M. Huffenberger, B. P. Crill, A. E. Lange +2
Accurate measurement of the cosmic microwave background (CMB) anisotropy requires precise knowledge of the instrument beam. We explore how well the Planck beams will be determined…
Fast Pixel Space Convolution for CMB Surveys with Asymmetric Beams and Complex Scan Strategies: FEBeCoP
S. Mitra, G. Rocha, K. M. Górski +4
Precise measurement of the angular power spectrum of the Cosmic Microwave Background (CMB) temperature and polarization anisotropy can tightly constrain many cosmological models an…
