Recent results on magnetars
Abstract
Several observations obtained in the last few years indicate that Soft Gamma-ray Repeaters (SGRs) and Anomalous X-ray Pulsars (AXPs) are basically a single class of isolated neutron stars. Their properties are well explained by the magnetar model, based on neutron stars powered by magnetic fields as high as 10^14 -10^15 G. Here I report some recent results obtained for the transient Soft Gamma-ray Repeater SGR 1627-41, that started a new outburst after about 10 years from the previous one, and for the Anomalous X-ray Pulsar 1E 1547.0-5408. The latter source recently showed a remarkable bursting activity, that reinforces the similarity between AXPs and SGRs.
