Swift observes a new outburst from the Supergiant Fast X-ray Transient AX J1845.0-0433
Abstract
Swift observed a new outburst from the SFXT AX J1845.0-0433/IGR J18450-0435. The Swift/BAT triggered on it on 2012 May 05 at 01:44:39 UT (image trigger=521567).
Using the BAT data set from T-239 to T+963 s from the recent telemetry downlink, we report that the mask-weighted light curve shows the source already in outburst when it came into the BAT FoV during a pre-planned slew. Emission continues at the 0.013 ph/cm2/s level out past T+963 s.- Publication:
