Abstract

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 8.8σ. The measured flux above 1 TeV is (2.5±0.4)×10⁻¹²cm⁻²s⁻¹ near inferior conjunction and (7.8±2.8)×10⁻¹³cm⁻²s⁻¹ near superior conjunction. The pulsar wind nebula HESS J1825-137 is detected with a statistical significance of 6.7σ and a measured flux above 1 TeV of (3.9±0.8)×10⁻¹²cm⁻²s⁻¹.
