All-sky component separation in the presence of anisotropic noise and dust temperature variations
V. Stolyarov, M. P. Hobson, A. N. Lasenby +1
We present an extension of the harmonic-space maximum-entropy component separation method (MEM) for multi-frequency CMB observations that allows one to perform the separation with…

Foreground separation using a flexible maximum-entropy algorithm: an application to COBE data
R. B. Barreiro, M. P. Hobson, A. J. Banday +4
A flexible maximum-entropy component separation algorithm is presented that accommodates anisotropic noise, incomplete sky-coverage and uncertainties in the spectral parameters of…
