Multipole vector anomalies in the first-year WMAP data: a cut-sky analysis
P. Bielewicz, H. K. Eriksen, A. J. Banday +2
We apply the recently defined multipole vector framework to the frequency-specific first-year WMAP sky maps, estimating the low-l multipole coefficients from the high-latitude sky…
CMB component separation by parameter estimation
H. K. Eriksen, C. Dickinson, C. R. Lawrence +9
We propose a solution to the CMB component separation problem based on standard parameter estimation techniques. We assume a parametric spectral model for each signal component, an…
Astro-ph communication: Simulations of the WMAP Internal Linear Combination sky map
H. K. Eriksen, A. J. Banday, K. M. Gorski +1
Following this astro-ph communication, we release a set of 10,000 WMAP ILC simulations, produced as described by Eriksen et al. (2004). We strongly encourage that an analysis of th…
Evidence of vorticity and shear at large angular scales in the WMAP data: a violation of cosmological isotropy?
T. R. Jaffe, A. J. Banday, H. K. Eriksen +2
Motivated by the large-scale asymmetry observed in the cosmic microwave background sky, we consider a specific class of anisotropic cosmological models -- Bianchi type VII_h -- and…
