Kolmogorov analysis detecting radio and Fermi gamma-ray sources in cosmic microwave background maps

TL;DR

This paper demonstrates that the Kolmogorov stochasticity parameter can effectively detect point radio and gamma-ray sources in cosmic microwave background maps, revealing sources not listed in earlier catalogs.

Contribution

It introduces a novel application of the Kolmogorov stochasticity parameter for source detection in CMB maps, successfully identifying previously unlisted sources.

Findings

Detected sources coinciding with known radio and gamma-ray sources.

Identified new sources later confirmed by updated catalogs.

Validated the method's effectiveness in source detection.

Abstract

The Kolmogorov stochasticity parameter is shown to act as a tool to detect point sources in the cosmic microwave background (CMB) radiation temperature maps. Kolmogorov CMB map constructed for the WMAP's 7-year datasets reveals tiny structures which in part coincide with point radio and Fermi/LAT gamma-ray sources. In the first application of this method, we identified several sources not present in the then available 0FGL Fermi catalog. Subsequently they were confirmed in the more recent and more complete 1FGL catalog, thus strengthening the evidence for the power of this methodology.
