Bayesian blind component separation for cosmic microwave background observations
Abstract. We present a technique based on the Expectation-Maximization (EM) algorithm for the separation of the components of noisy mixtures in the Fourier plane. We perform a semi-blind joint estimation of components, mixing coefficients and noise rms levels. A priori information for the spatial spectrum of the components and for the mixing coefficients can be naturally included in the algorit...
متن کاملCosmic Microwave Background Polarisation: foreground contrast and component separation
We evaluate the expected level of foreground contamination to the cosmic microwave background (CMB) polarised radiation, focusing on the diffuse emission from our own Galaxy. In particular, we perform a first attempt to simulate an all sky template of polarised emission from thermal dust. This study indicates that the foreground contamination to CMB B modes is likely to be relevant on all frequ...
متن کاملComponent Separation for Cosmic Microwave Background Data: a Blind Approach Based on Spectral Diversity
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. The method allows to estimate on a set of observation maps the power spectra of various components present in CMB data, their contribution levels in each detector and the noise levels. The method accounts for the instru...
متن کاملMulti-component power spectra estimation method for multi-detector observations of the Cosmic Microwave Background
We present a new method for multi-component power spectra estimation in multifrequency observations of the CMB. Our method is based on matching the cross and auto power spectra of observation maps to their expected values. All the component power spectra are estimated, as well as their mixing matrix. Noise power spectra are also estimated. The method has been applied to full-sky Planck simulati...
