Scientific paper

We present preliminary results on the spectral modeling of magnetars' X-ray emission through a resonant cyclotron scattering model. We fit the soft and hard X-ray spectrum of all magnetars with a main component representing a thermal emission from the neutron star surface which scatters (through a resonant cyclotron scattering process) on a slab of mildly relativistic magnetospheric electrons. Here we present the results obtained for the 0.5-200 keV (XMM-Newton+INTEGRAL) spectrum of the anomalous X-ray pulsar 1E 1841-045, and the 0.5-10 keV (XMM-Newton) variable spectrum of the transient magnetar XTE J1810-197.
