On the detection of point sources in CMB maps
  We use the Wilkinson Microwave Anisotropy Probe 7-year data (WMAP7) to
further probe point source detection technique in the sky maps of the cosmic
microwave background (CMB) radiation. The method by Tegmark et al. for
foreground reduced maps and the Kolmogorov parameter as the descriptor are
adopted for the analysis of WMAP satellite CMB temperature data. Part of the
detected points coincide with point sources already revealed by other methods.
However, we have also found 2 source candidates for which still no counterparts
are known, and identified 7 point sources listed in Planck Early Release
Compact Source Catalogue as high reliability sources.
