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…
Fast and Efficient Template Fitting of Deterministic Anisotropic Cosmological Models Applied to WMAP Data
T. R. Jaffe, A. J. Banday, H. K. Eriksen +2
We explore methods of fitting templates to cosmic microwave background (CMB) data, and in particular demonstrate the application of the total convolver algorithm as a fast method o…
Foreground Subtraction of Cosmic Microwave Background Maps using WI-FIT (Wavelet based hIgh resolution Fitting of Internal Templates)
F. K. Hansen, A. J. Banday, H. K. Eriksen +2
We present a new approach to foreground removal for Cosmic Microwave Background (CMB) maps. Rather than relying on prior knowledge about the foreground components, we first extract…
