Magnetars are neutron stars mainly powered by their huge magnetic fields. They go through long stretches of quiescence interrupted by periods of activity via short X-ray bursts large giant flares and yearly-timescale X-ray outbursts. Lately several normal pulsars showed magnetar-like emission and FRB-like events were observed during a short X-ray burst prompting important questions on the exact physics and reach of the magnetar phenomenon. We propose a Joint XMM (110ks) and NRAO/GRB (14hr) ToO program aimed at gather new physical insights on magnetars surface field configuration and magnetosphere search for radio pulsed emission and for (quasi-)simultaneous X-ray and radio bursts. We might trigger this program on any source that will undergo a magnetar-like outburst during AO21. [truncated! Please see actual data for full text]
