Description
We report the discovery with Fermi/LAT of γ-ray emission from three radio-loud narrow-line Seyfert 1 galaxies: PKS 1502+ 036 (z= 0.409), 1H 0323+ 342 (z= 0.061), and PKS 2004− 447 (z= 0.24). In addition to PMN J0948+ 0022 (z= 0.585), the first source of this type to be detected in γ rays, they may form an emerging new class of γ-ray active galactic nuclei (AGNs). These findings can have strong implications on our knowledge about relativistic jets and the unified model of the AGN.
