|Description||Hard X-ray emission from magnetars was discovered by INTEGRAL, and generally comprises more luminosity than is seen below 10 keV. However, the origin of this powerful hard X-ray emission is unknown. NuSTAR is a recently launched NASA mission, the first focusing hard X-ray telescope. Operating in the 3-79 keV band, it has sensitivity ~100x better than previous telescopes in this energy range. NuSTAR is a superb instrument for studying the hard X-ray emission from magnetars. Here we propose simultaneous XMM and NuSTAR observations of magnetar 1E 1048.1-5937, to obtain high-quality broadband X-ray spectrum to test a proposed correlation between spectral turnover and magnetic field, and for comparison with the predictions of a new model for magnetar hard X-ray emission.|

|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.
