Does the contribution of infrared and submillimeter sources reveal itself at low harmonics of the CMB?

Verkhodanov, O. V.; Naiden, Ya. V.

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 t…

On two low harmonics of CMB correlation maps

Verkhodanov, O. V.; Naiden, Ya. V.; Keshelava, T. V.

We have analyzed two powerful correlation harmonics (ℓ = 3and ℓ = 6) found in the correlation of the ILC WMAP signal with the submillimeter and infrared range data from the FSC IRAS and Planck catalogs. The mode phases of thesemultipoles were computed. In the spots we have found in the harmonics, the source counts were made from the NVSS, FIRST, F…
