Multiwavelength ctp of Fermi gamma-ray sources

The main goal is to identify new blazars and/or new active galactic nuclei (AGNs) emitting at GeV energies [like (Narrow Line) Seyfert-1 and radio galaxies]. We focus on sky regions observed by the Swift satellite that overlap with the reported positions of the UGSs.

Since our primary interest lies in extra-galactic sources, we focus on UGSs located outside the Galactic plane (|b|>10{deg}). Due to the large number of sources (about 1800 UGS), we developed a pipeline to automatised the search for counterparts and significantly reduce the computational time for the analysis. Our association process begins by identifying potential X-ray counterparts for each UGS; if one is found, we further look for corresponding radio and optical counterparts in the X-ray counterpart error box, thus minimizing ambiguities.
