Abstract (from CDS):
We observed the bright unidentified TeV g-ray source HESS J1616-508 with the X-ray Imaging Spectrometers onboard the Suzaku satellite. No X-ray counterpart was found to a limiting flux of 3.1 x 10–13 erg/s/cm2 in the 2-10keV band, which is some 60-times below the g-ray flux in the 1-10TeV band. This object is bright in TeV g-rays, but very dim in the X-ray band, and thus is one of the best examples in the Galaxy of a ``dark particle accelerator.'' We also detected soft thermal emission with kT ∼0.3-0.6 keV near the location of HESS J1616-508. This may be due to a dust-grain scattering halo from the nearby bright supernova remnant RCW 103.
