Study of High Energy Emission from Relativistic Jets with VERITAS

Abstract. VERITAS is an imaging atmospheric Cherenkov telescope array carrying out observations of the gamma-ray sky at energies above 100 GeV. Located in southern Arizona, VERITAS consists of an array of four telescopes, and carries out a comprehensive observing program for Galactic and extragalactic high energy sources. Observations of astrophysical objects in the TeV band are sensitive probes of highly energetic processes occurring in these sources. The majority of the extragalactic sources detected at TeV energies are active galaxies of the blazar class, sources where we view the jet nearly along its axis. In this report we present recent results from the VERITAS extragalactic program, focusing on blazars
