Abstract:
Among the gamma-ray sources identified through the Fermi Large Area Telescope, approximately one-third of them currently defies a clear association with any specific class of astrophysical sources.
We will study their energy spectrum distribution – one of the most promising features to unveil the origin of these puzzling gamma-ray sources.
We will introduce a statistical model to describe the distribution of the unassociated sources, including both astrophysical components and dark matter.
Once properly fitted on 4FGL catalog data, we will use this model to draw bounds on the annihilation cross-section of Dark Matter and give a probabilistic classification of the unassociated sources.
