Correlations in Cosmological and Non-Cosmological Signals
Abstract
We analyze the correlations in the cosmological cosmic microwave background radiation and those of point sources, i.e. galaxies and quasars. The Wilkinson Microwave Anisotropy Probe 7-year data are used along with the method developed by Tegmark et al. for obtaining of foreground reduced maps, combined with the Kolmogorov parameter. We obtain the cross correlations in the temperature and K-maps, and report the detection of still unidentified point sources, along with the previously known ones, and hence, showing the power of the applied technique.
