VERITAS Detection of LS 5039 and HESS J1825-137

High Energy Astrophysical Phenomena 2020-01-13 v1

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 8.8σ8.8\sigma. The measured flux above 1 TeV is (2.5±0.4)×1012cm2s1(2.5 \pm 0.4) \times 10^{-12} \rm \, cm^{-2} \, s^{-1} near inferior conjunction and (7.8±2.8)×1013cm2s1(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 6.7σ6.7\sigma and a measured flux above 1 TeV of (3.9±0.8)×1012cm2s1(3.9 \pm 0.8) \times 10^{-12} \rm \, cm^{-2} \, s^{-1}.
