The remnant of the supernova of 1006 AD, the remnant first showing evidencefor the presence of X-ray synchrotron emission from shock-acceleratedelectrons, was observed for ~1000 ksec with INTEGRAL for the study of electronacceleration to very high energies. The aim of the observation was tocharacterize the synchrotron emission, and attempt to detect non-thermalbremsstrahlung, using the combination of IBIS and JEM-X spatial and spectralcoverage. The source was detected with JEM-X between 2.4 and 8.4 keV bands, andnot detected with either ISGRI or SPI above 20 keV. The ISGRI upper limit isabout a factor of four above current model predictions, but confirms thepresence of steepening in the power-law extrapolated from lower energies (< 4keV).Comment: 5 pages, 3 figures, 1 table, accepted for publication in the Astrophysical Journa
