  In the recent years massive protostars have been suggested to be high-energy
emitters. 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.
