Energy partition in SN 1006: thermal gas comma relativistic particles comma magnetic field

We propose to carry out a deep 1 Ms XMMNewton observation of the entire SN 1006supernova remnant (SNR) for a major breakthrough in answering key questions onthe physics of SNRs, related to particle acceleration at their shock, magneticfield amplification, heating of the electrons and ions at the shock, abundancesand distribution of the chemical elements in the ejecta. This historical type IaSNR exhibits a dual nature in Xrays with a bipolar nonthermal morphology likein radio, superposed on a fainter extended thermal emission. It is one of thebest examples of shock acceleration of cosmicray electrons to energiesapproaching the knee.. of the cosmicray spectrum and gathers the mostimportant issues concerning SNR physics. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
