RELATIVISTIC JETS IN GAMMA-RAY-EMITTING NARROW-LINE SEYFERT 1 GALAXIES

Before the launch of 5th marine division patch the Fermi Gamma-ray Space Telescope satellite only two classes of active galactic nuclei (AGN) were known to generate relativistic jets and thus to emit up to the γ -ray energy range: blazars and radio galaxies, both hosted in giant elliptical galaxies.The discovery by the Large Area Telescope (LA
