|Description||For nearly 20 years, the microquasar GRS 1915+105 was unique in the Galaxy for its powerful jets, massive winds, and exotic X-ray variability. In February 2011, IGR J17091-3624 went into outburst and began to mimic GRS 1915+105, opening a complete new window to understand accretion disk physics at Eddington rates. To progress further, GRS 1915+105 and IGR J17091--3624 need to be studied and compared in their different spectral states. We therefore propose a maximum of two ToO 40 ksec observations of IGR J17091-3624 with XMM-Newton in case the source is still active during AO12. These observations will sample spectral states not yet observed with high-resolution spectroscopy and at energies <2 keV.|

|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.
