RXJ1713.7-3946: a unique synchrotron-dominated shell-like SNR

We propose to finish the entire mapping of the supernova remnant RX J1713.73946within 4 pointings of 20 ks to study one of the most fascinating cosmicrayaccelerators known today. Our objectives are 1) to obtain the full and mostdetailed description of the morphology of the Xray synchrotron emission 2) tomap the variations of the spectral index and the Xray absorption 3) to searchfor spatial correlations with the TeV gammaray emission recently imaged withthe HESS Cerenkov telescopes 4) to compare how particle acceleration proceedswhen the SNR is interacting with molecular clouds or with a tenuous ambientmedium truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
