Long-term monitoring of bright blazars with a dedicated Cherenkov telescope
2009
Flaring activity of Active Galactic Nuclei (AGN) in VHE γ-ray
astronomyis observed on timescales from minutes to years and can be explained either by the interaction of relativistic jets with the surrounding material or by imprints of the central engine, like temporal modulation caused by binary systems of
supermassive black holes. The key to answer those questions lies in combining 24/7 monitoring with short high sensitivity exposures as provided by the third generation γ-ray
astronomyinstruments like MAGIC, VERITAS and H.E.S.S. The long-term observations can be provided by a
global networkof small robotic Cherenkov
telescopes.1 As a first step, we are currently setting up a dedicated Cherenkov
telescope, which will carry out joint observations with the Whipple 10 m
telescopefor AGN monitoring. The new
telescopewill be designed for low costs but high performance by upgrading one of the former
HEGRA
telescopes, still located at the MAGIC site on the Canary Island of La Palma (Spain). The main novelti...
