Abstract
VERITAS is an array of four 12-m diameter imaging atmospheric-Cherenkov telescopes located in southern Arizona. Its aim is to study the very high energy (VHE: E > 100 GeV) gamma-ray emission from astrophysical objects. In addition to the study of blazars, the VERITAS extragalactic science program develops a comprehensive observational program of extragalactic non-blazar sources. The study of Active Galactic Nuclei (AGN) is intensively pursued through the large MWL observational campaign on non-blazar radio galaxies. The success of these MWL campaigns has for the first time provided insights to the inner structures of jets responsible for gamma-ray emission. The problem of the origin and acceleration of ultra-high energy cosmic rays is pursued through the observation of the starburst galaxy M 82, whose detection at VHE delivers important insights on the possible acceleration mechanisms.…
