Objective
We propose a coordinated investigation on data analysis and theoretical interpretation of the intensity fluctuations of the CMB radiation. This investigation will extend the one already existing within the Human capital and Mobility programme of the EC entitled "The Cosmic Microwave Background Radiation:Measurements and Interpretation".
In analysing the data statistical optimitation for a multi-frequency experiment will be carried out for search of the cosmologiical signal and its separation from the other foreground contributions. To tes the accuracy of future experiments correlations between input parameters and results will be performed. New alternative statistical methods will be used to obtain information on the distribution of the CMB temperature fluctuations and, in particular, to test the Gaussian character of the fluctuations. In the search for new anisotropy limits and detections, geometrical analysis of the temperature maps will be carried out as an alternative method to the standard analysis of temperature fluctuations. From the theoretical point for view, a precise modelization of the emission from the several galactic contributions will be required in order to disentangle the galactic and cosmic radiations. The nes anisotropy measurements of the CMB on large angular scales will be intrinsic CMB temperature fluctuations for the large-scale structure will be studied via linear (sach-wolf) and non-linear effects. On intermedite scales (Scales smaller than 1 degree) the anisotropiy expected in non-standard recombination models (vishniac effect) will be estimated for several cosmological scenarios, containing different barionic contents, and confronted with the new limits or detections.
