Soft-γ-ray repeaters (SGRs) and anomalous X-ray pulsars (AXPs) are slowly rotating, isolated neutron stars that sporadically undergo episodes of long-term flux enhancement (outbursts) generally accompanied by the emission of short bursts of hard X-rays. This behaviour can be understood in the magnetar model, according to which these sources are mainly(More)
Within the magnetar scenario, the " twisted magnetosphere " model appears very promising in explaining the persistent X-ray emission from the Soft Gamma Repeaters and the Anomalous X-ray Pulsars (SGRs and AXPs). In the first two papers of the series , we have presented a 3D Monte Carlo code for solving radiation transport as soft, thermal photons emitted by(More)
The anomalous X-ray pulsars and soft γ-repeaters are peculiar high-energy sources believed to host a magnetar, an ultra-magnetized neutron star with surface magnetic field in the PetaGauss range. Their persistent, soft X-ray emission exhibit a two component spectrum, usually modeled by the su-perposition of a blackbody and a power-law tail. It has been(More)
