Evidence of an Inverse Compton Origin for the Tev Emission from the Supernova Remnant G347.3-0.5
Abstract
We present the results of a joint spectral analysis of some radio, X-ray and gamma-ray data for the supernova remnant G347.3-0.5. The shell-type remnant was discovered in the ROSAT All-Sky Survey data. The X-ray flux is relatively large and dominated by synchrotron radiation. G347.3-0.5 is one of only a few remnants reported to emit TeV gamma rays. Both the CANGAROO and HESS collabortations have published gamma-ray spectra for the source. Both of these spectra, which are inconsistent with one another, are considered as part of the analysis. The differences between these spectra are discussed. The physical process responsible for the TeV emission remains controversial. We review the three possible mechanisms---inverse Compton scattering, the decay of neutral pions and nonthermal bremsstrahlung---and argue that the results of our spectral analyses favor inverse Compton scattering.
