Abstract
Based on the first 4 years of Fermi operation, the third catalogue of active galactic nuclei detected by the Large Area Telescope on board theFermi satellite included approximately 1600 gamma-ray sources located at high Galactic latitudes, and statistically associated with AGN.
The large majority of these AGN are blazars, but also different types of gamma-ray emitting AGN such as radio galaxies and narrow-line Seyfert 1 galaxies are detected.When combined with contemporaneous ground- and space-based observations, Fermi-LAT achieves its full capability to characterize the jet structure and the emission mechanisms at work in radio-loud AGN.
In this talk I willdiscuss the radio-to-gamma-rays properties of blazars, radio galaxies, and narrow-line Seyfert 1 galaxies, highlighting major findings and open questions regarding the physics of AGN in the Fermi era.
