Abstract
© 2014, Institute of Astronomy and Rozhen NAO. All rights reserved.We report about the finding of two peculiar radio sources inside the 95% confidence ellipse of the the gamma-ray source 2FGL J0221.4+6257c detected by the Fermi Large Area Telescope. Both of them look particularly interesting since their morphologies, and the existence of point-like infrared counterparts, strongly point to active galactic nuclei with highly beamed relativistic jets. A blazar, or a flat spectrum radio quasar nature is tentatively proposed for the brightest one based on the extreme brightness contrast of its jet and counterjet. The possibility that this object is where the gamma-ray photons originate deserves serious consideration.
