Title: Studies of active galaxies in the GLAST era

Abstract: Active galaxies, presumably powered by flow of galaxian matter onto sumermassive black holes, are amongst the most luminous celestial sources. Their isotropic radiation is sometimes accompanied by Doppler-boosted emission from a relativistic jet. The spectra emitted by such jets often extend from the lowest accessible radio frequencies to the most energetic (TeV) observable gamma-rays. This presentation will cover the new results that are inferred from current X-ray and soft gamma-ray observations of jet-dominated AGN, and will present the prospects for understanding their structure with the launch of the Gamma-ray Large Area Space Telescope, slated for launch in May 2008.
