Description
This work is motivated by prior observations of extended TeV gamma-ray sources, such as HESS J1813-178, and their GeV counterparts. In this example case, two unidentified Fermi-LAT point sources, 3FGL J1814.0-1757c and 3FGL J1814.1-1734c, were found in the region. Subsequent multiwavelength analysis combining TeV and GeV data found a single extended source to be a better description of the emission in this region. HESS J1813-178 is currently classified as a PWN candidate and exemplifies the challenges posed by extended sources, where intricate morphology can lead to the misidentification of multiple point-like sources instead of a single entity. Our study utilizes clustering techniques in the spatial domain and conducts a spectral analysis of the cluster candidates to address these challenges by refining methods for source identification, particularly focusing on the potential extension of sources within the galactic plane.
