Observations of the Giant Radio Galaxy M87 in the 100 GeV Energy Domain with the MAGIC Telescope — •Jordi Albert and Thomas Bretz — Institut für Theoretische Physik und Astrophysik der Universität Würzburg, Am Hubland, 97074 Würzburg

The giant radio galaxy M87, one of the most interesting active galaxies because of its dimensions and proximity, has been subject to extensive investigations from radio to X-ray wavebands, and recently also in gamma rays. Preliminary results from the observation campaign carried out with the MAGIC Cherenkov Telescope in spring 2005 and winter 2006, operating in the unexplored 100 GeV energy domain of gamma rays from M87, will be presented. Testing models for radiation processes in large scale non-thermal jets and origin of the high-energy extragalactic cosmic rays, as well as indirect search for dark matter, are the main motivations for these observations.
