30TH INTERNATIONAL COSMIC RAY CONFERENCE Gamma-ray blazars: the combined AGILE and MAGIC views

Abstract: We describe the emission properties of blazars, i.e. the AGNs that, due to their peculiar orientation w.r.t. the observer, allow the most penetrating and direct view of their central engine. After showing that the extragalactic GeV-TeV sky is dominated by blazars of various types, we discuss the kind of blazars that are likely to be jointly detected by AGILE and MAGIC. Blazars Supermassive black holes (SMBHs) reside in the cores of most galaxies. The fueling of SMBHs by infalling matter produces the spectacular activity observed in active galactic nuclei (AGNs). The current AGN paradigm includes a central en-gine, most likely a SMBH, surrounded by an accre-tion disk and by fast-moving clouds, which emit Doppler-broadened lines ([26, 19]). More distant clouds emit narrower lines. Absorbing material in some flattened configuration (e.g., a torus) ob
