THE DISCOVERY OF A PULSAR WIND NEBULA AROUND THE MAGNETAR CANDIDATE AXP 1E1547.0-5408

Show affiliationsWe report the detection of extended emission around the anomalous X-ray pulsar 1E1547.0-5408 using archival data of the Chandra X-ray satellite. The extended emission consists of an inner part, with an extent of 45'', and an outer part with an outer radius of 2
9, which coincides with a supernova remnant shell previously detected in the radio. We argue that the extended emission in the inner part is the result of a pulsar wind nebula (PWN), which would be the first detected PWN around a magnetar candidate. Its ratio of X-ray luminosity versus pulsar spin-down power is comparable to that of other young PWNe, but its X-ray spectrum is steeper than most PWNe. We discuss the importance of this source in the context of magnetar evolution.
