Source separation on astrophysical data sets from the WMAP satellite
G. Patanchon, J. Delabrouille, J. -F. Cardoso
This paper presents and discusses the application of blind source separation to astrophysical data obtained with the WMAP satellite. Blind separation permits to identify and isolat…
Component separation for Cosmic Microwave Background data: a blind approach based on spectral diversity
G. Patanchon, H. Snoussi, J. F. Cardoso +1
We present a blind multi-detector multi-component spectral matching method for all sky observations of the cosmic microwave background, working on the spherical harmonics basis. Th…
Blind separation of noisy Gaussian stationary sources. Application to cosmic microwave background imaging
Jean-Francois Cardoso, Hichem Snoussi, Jacques Delabrouille +1
We present a new source separation method which maximizes the likelihood of a model of noisy mixtures of stationary, possibly Gaussian, independent components. The method has been…
Simulations of Sunyaev-Zel'dovich maps and their applications
J. Delabrouille, J. -B. Melin, J. G. Bartlett
We describe a fast method to simulate in a semi-analytical way consistent maps of the thermal, kinetic and polarised Sunyaev-Zel'dovich effect, featuring both cluster spatial corre…
A Sunyaev-Zel'dovich map of the massive core in the luminous X-ray cluster RXJ1347-1145
E. Pointecouteau, M. Giard, A. Benoit +5
We have mapped the Sunyaev-Zel'dovich decrement (hereafter SZ) in the direction of the most luminous X-ray cluster known to date, RXJ1347-1145, at z=0.451. This has been achieved w…
Scanning strategies for the Planck mission
J. Delabrouille, J. -L. Puget, R. Gispert +1
This paper discusses the problem of the optimisation of the scanning strategy for the Planck mission.
