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]
