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…
Harmonic analysis of cosmic microwave background data I: ring reductions and point-source catalogue
Floor van Leeuwen, Anthony D. Challinor, Daniel J. Mortlock +7
We present a harmonic model for the data analysis of an all-sky cosmic microwave background survey, such as Planck, where the survey is obtained through ring-scans of the sky. In t…
All-sky component separation for the Planck mission
V. Stolyarov, M. P. Hobson, M. A. J. Ashdown +1
An harmonic-space maximum-entropy method (MEM) is presented for separating the emission from different physical components in all-sky observations by the forthcoming Planck satelli…
