Search for TeV emission from the region around PSR B1706-44 with the HESS experiment

aap, 432:L9-L12.

The region around PSR B1706-44 has been observed with the HESS imaging atmospheric Cherenkov telescopes in 2003. No evidence for gamma-ray emission in the TeV range was found at the pulsar position or at the radio arc which corresponds to the supernova remnant G 343.1-2.3. The 99% confidence level flux upper limit at the pulsar position is F^ul(E>350 GeV) = 1.4 × 10^-12 s^-1 cm^-2 assuming a power law (dN/dE ∝ E^-Gamma) with photon index of Gamma = 2.5 and F^ul(E > 500 GeV) = 1.3 × 10^-12 s^-1 cm^-2 without an assumption on the spectral shape. The reported upper limits correspond to 8% of the flux from an earlier detection by the CANGAROO experiment.
