VERITAS Detection of LS 5039 and HESS J1825-137


Abstract in English

With 8 hours 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 $8.8sigma$. The measured flux above 1 TeV is $(2.5 pm 0.4) times 10^{-12} rm , cm^{-2} , s^{-1}$ near inferior conjunction and $(7.8 pm 2.8) times 10^{-13} rm , cm^{-2} , s^{-1}$ near superior conjunction. The pulsar wind nebula HESS J1825-137 is detected with a statistical significance of $6.7sigma$ and a measured flux above 1 TeV of $(3.9 pm 0.8) times 10^{-12} rm , cm^{-2} , s^{-1}$.
