XMM-Newton observation of the new SGR 0501+4516 in its return to in quiescence

We ask for a 50ks XMMNewton observation of the newly discovered Soft GammaRepeater SGR 0501+4516, aimed at a deep study of the source in its return toquiescence state. The transient Xray behaviour of SGR0501+4516 was caught fromthe beginning of the outburst by our AO7 XMMNewton ToO monitoring program,allowing us to study in unprecedented detail the timing and spectral evolutionof the outburst decay of a SGR. We now request a further pointing in order tocomplete the study of the evolution of the source to characterize its quiescentstate, and single out permanent spectral/timing changes induced by the outburst. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
