|Title||Observing extreme SFXTs with XMM|
|Author||Dr Enrico Bozzo|
|Description||We propose a 130 ks-long XMM-Newton observation of the most extreme among the Supergiant Fast X-ray Transient, IGR J17544 2619, to unveil the mechanism regulating the unique behavior of these objects in the X-ray domain. This deep observation with XMM will secure: (i) enough sensitivity to study with the required accuracy soft spectral components, which are the most reliable tracers of the donor wind structure and can be used to efficiently probe the accretion flow geometry in wind-fed systems; (ii) catch at least one bright burst and 7-10 smaller flares, permitting an accurate spectral and statistical analysis of the triggering mechanism; (iii) measure pulsations down to pulsed fractions of 4-5% and spin periods of 3-4 ks, expected for magnetars in binaries.|

|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.
