The MAGIC extragalactic sky

Abstract

The MAGIC telescope, with its 17-m diameter mirror, is currently the largest single-dish Imaging Air Cherenkov Telescope. It is located on the Canary Island of La Palma, at an altitude of 2200 m above sea level, and is operating since 2004. The accessible energy range is in the very high energy (VHE, E>100 GeV) gamma-ray domain, and roughly 40% of the duty cycle is devoted to observation of extragalactic sources. Due to the lowest energy threshold (25 GeV), it can observe the deepest universe, and it is thus well suited for extragalactic observations. The strategies of extragalactic observations by MAGIC are manifold: long time monitoring of known TeV blazars, detailed study of blazars during flare states, multiwavelength campaigns on most promising targets, and search for new VHE gamma-ray emitters. In this talk, highlights of observations of extragalactic objects will be reviewed.
