The post-awakening of the transient bursting AXP in Westerlund 1

On September 2006 an intense (10^39 ergs) and short (20ms) burst was detected bySwift from the candidate Anomalous Xray Pulsar CXOU J164710.2455216. A Swiftobservations carried out 13 hours later found that the AXP entered in a rareoutburst phase and measured a flux level 300 times brighter then that inquiescence. Subsequent Swift, Chandra, XMM and SUZAKU followup observationsmonitored the initial phases of the source outburst allowing to infer veryimportant information for this source. Both the spectral and timing propertiesof CXOU J164710.2455216 drastically changed and are still evolving after oneyear. The present proposal is aimed at following the evolution of the mainspectral/timing parameters of the second confirmed bursting transient AXP. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
