Abstract: The VERITAS observatory is an imaging atmospheric Cherenkov telescope array located in southern Arizona and covers an energy range between 100GeV and 30TeV. The VERITAS collaboration pursues a rigorous observing program that targets a range of key science objectives in astrophysics and particle physics; the understanding of the origin of cosmic rays, the search for supersymmetric dark matter self-annihilation, illuminating the connection between black holes and relativistic jets and constraints to the cosmological diffuse infrared background. We provide a summary of results from the first two years of observations with the full 4-telecope array reported at RICAP09. [Copyright &y& Elsevier]

With 8 h of observations, VERITAS confirms the detection of two very high energy gamma-ray sources. The gamma-ray binary LS 5039 is detected with a statistical significance of 8.8 σ. The measured flux above 1 TeV is (2.5 ± 0.4) × 10 − 12 cm − 2 s − 1 near inferior conjunction and (7.8 ± 2.8) × 10 − 13 cm − 2 s − 1 near superior conjunction. The pulsar wind nebula HESS J1825-137 is detected with a statistical significance of 6.7 σ and a measured flux above 1 TeV of (3.9 ± 0.8) × 10 − 12 cm − 2 s − 1 . [ABSTRACT FROM AUTHOR]
