VERITAS Detection of LS 5039 and HESS J1825-137

Abstract

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