AGN Observations with VERITAS

摘要

The VERITAS collaboration operates an array of four imaging atmospheric Cherenkov telescopes in southern Arizona. Regular observations with all four telescopes started in 2007. Active galactic nuclei (AGN) are an portant component of the observation program. During the first 1.5 years new TeV Υ-ray emitting blazars were discovered and a variety of known Υ-ray AGN were measured with high precision - often within coordinated multi-wavelength campaigns. The results and interpretation of the AGN observations are pre-sented.
