Component separation with flexible models. Application to the separation of astrophysical emissions
Jean-Francois Cardoso, Maude Martin, Jacques Delabrouille +2
This paper offers a new point of view on component separation, based on a model of additive components which enjoys a much greater flexibility than more traditional linear componen…
Diffuse source separation in CMB observations
J. Delabrouille, J. -F. Cardoso
We review issues and methods for diffuse component separation in the context of Cosmic Microwave Background observations. The revised version contains a paragraph on FastICA and it…
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…
