Shock modification at the rim of SN 1006 | Marco Miceli ( INAF- Osservatorio Astronomico di Palermo )

We present the results of the analysis of a Large Program of deep XMM-Newton observations of SN1006. We focus on the rim of the supernova remnant to derive important constraints for the shock acceleration process and for the back-reaction of the accelerated particles on the evolution of the remnant. The physical properties of the shocked ambient medium are expected to be modified by the acceleration process but up to now X-ray emission from the shocked ISM has never been detected in SN1006. The new data allow us to detect the shocked ISM and to ascertain whether the particle acceleration alters its post-shock properties. The comparison of our results with predictions from detailed MHD models of a modified supernova remnant can provide important physical insight on the physics of diffusive shock acceleration
