Scientific paper

We have computed and studied the mosaic correlation maps of the ILC WMAP microwave background data with the positions of infrared and submillimeter sources. Using the histograms of the signal values in pixels and angular power spectra, we studied the statistical properties of these maps. We discovered similar behavior of a number of harmonics in the maps of correlations with the FSC IRAS, 2MASX and Planck catalog objects. The most prominent multipoles among them, which may reflect the actual distribution of radiation sources are the ℓ = 6 for the FSC and Planck data, and ℓ = 3 for the Planck source data.
