Description Magnetars are young isolated neutron stars with bright broad-band 0.5-200 keV persistent X-ray emission, caused by the decay of the extremely high internal and external magnetic field. Here we propose a simultaneous NuSTAR+XMM-Newton observation of one of the brightest magnetars, 1RXSvirgulJ170849.0 - 400910. This source shows the most drastic changes in pulse profile shape with energy as well as the most complex spectral variations with phase. The proposed observation will allow us to perform broad-band high-sensitivity fine-resolution phase-resolved spectroscopy, crucial to disentangle the contribution from different spectral components in each phase bin. Such analysis would be the ultimate test for the currently available theoretical models for X-ray emission production in magnetars.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
