The Anomalous X‐ray Pulsar (AXP) 1E 1547.0–5408 reactivated in 2009 January with the emission of dozens of short bursts. Follow‐up observations with Swift/XRT and XMM‐Newton showed the presence of multiple expanding rings around the position of the AXP. These rings are due to scattering, by different layers of interstellar dust, of a very high fluence burst emitted by 1E 1547.0–5408 on 2009 January 22. Thanks to the exceptional brightness of the X‐ray rings, we could carry out a detailed study… Expand

THE DUST-SCATTERING X-RAY RINGS OF THE ANOMALOUS X-RAY PULSAR 1E 1547.0-5408
On 2009 January 22 numerous strong bursts were detected from the anomalous X-ray pulsar 1E 1547.0-5408. Swift/XRT and XMM-Newton/EPIC observations carried out in the following two weeks led to theExpand

TLDR
Using the GBM data, this work identified a ~150-s-long enhanced persistent emission during 2009 January 22 that exhibited intriguing timing and spectral properties: clear pulsations up to ~110 keV at the spin period of the neutron star, an additional blackbody component required for the enhanced emission spectra with kT ~ 17 keV, and a pulsed fraction that is strongly energy dependent and highest in the 50-74 keV energy band.
