Harmonic analysis of cosmic microwave background data II: from ring-sets to the sky
Anthony D. Challinor, Daniel J. Mortlock, Floor van Leeuwen +4
Despite the fact that the physics of the cosmic microwave background anisotropies is most naturally expressed in Fourier space, pixelised maps are almost always used in the analysi…
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…
