Estimating the spectral indices of correlated astrophysical foregrounds by a second-order statistical approach
A. Bonaldi, L. Bedini, E. Salerno +2
We present the first tests of a new method, the Correlated Component Analysis (CCA) based on second-order statistics, to estimate the mixing matrix, a key ingredient to separate as…

Separation of correlated astrophysical sources using multiple-lag data covariance matrices
L. Bedini, D. Herranz, E. Salerno +3
This paper deals with a source separation strategy based on second-order statistics, namely, on data covariance matrices estimated at several lags. In general, ``blind'' approaches…

Extracting cosmic microwave background polarisation from satellite astrophysical maps
C. Baccigalupi, F. Perrotta, G. De Zotti +5
We present the application of the Fast Independent Component Analysis ({\ica}) technique for blind component separation to polarized astrophysical emission. We study how the Cosmic…
