Abstract

The Swift/Burst Alert Telescope detected the first burst from 1E1841-045 in 2010 May with intermittent burst activity recorded through at least 2011 July. Here we present Swift and Fermi/Gamma-ray Burst Monitor observations of this burst activity and search for correlated changes to the persistent X-ray emission of the source. The T ₉₀ durations of the bursts range between 18 and 140ms, comparable to other magnetar burst durations, while the energy released in each burst ranges between (0.8-25) × 10 ³⁸erg, which is on the low side of soft gamma repeater bursts. We find that the bursting activity did not have a significant effect on the persistent flux level of the source. We argue that the mechanism leading to this sporadic burst activity in 1E1841-045 might not involve large-scale restructuring (either crustal or magnetospheric) as seen in other magnetar sources.
