Among the best candidates is IRAS 16547-4247, a protostar that presents a powerful outflow with clear signatures of interaction with its environment. This source has been revealed to be a potential high-energy source because it displays non-thermal radio emission of synchrotron origin, which is evidence of relativistic particles. To improve our understanding of IRAS 16547-4247 as a high-energy source, we analyzed XMM-Newton archival data and found that IRAS 16547-4247 is a hard X-ray source. We discuss these results in the context of a refined one-zone model and previous radio observations. From our study we find that it may be difficult to explain the X-ray emission as non-thermal radiation coming from the interaction region, but it might be produced by thermal Bremsstrahlung (plus photo-electric absorption) by a fast shock at the jet end. In the high-energy range, the source might be detectable by the present generation of Cherenkov telescopes, and may eventually be detected by Fermi in the GeV range.7 p.application/pdfeng(c) Springer Verlag, 2013EstelsAstronomia de raigs gammaAstronomia de raigs XJets (Astrofísica)Matèria interstel·larStarsGamma ray astronomyX-ray astronomyAstrophysical jetsInterstellar matterinfo:eu-repo/semantics/article6295192013-12-09info:eu-repo/semantics/openAccess
