摘要
Radio-loud sources with blazar-like properties, but having a jet that does not directly point in the direction of the observer are among the most interesting classes of gamma-ray emitters. These sources are known as Misaligned Active Galactic Nuclei (MAGN). Understanding MAGN properties is useful to improve the knowledge of blazar energetics. We searched for new MAGN candidates among the remaining blazars of uncertain type detected by the FermiLarge Area Telescope (LAT) using a methodology based on characterizing their radio morphology. We identified seven candidates associated with gamma-ray sources. Their features are compatible with a source with a misaligned relativistic jet consistent with the definition of MAGN.
