We propose to observe the Galactic microquasar 1E 1740.7-2942 for 80 ks, whilein the low-hard state, with EPIC-pn onboard XMM-Newton. This observation willallow us to detect the relativistically broadened iron line recently revealed inarchival Suzaku & XMM-Newton observations. Fits to this iron line will allow usto constrain the spin of the black hole and probe its relation to the presenceof large scale jets in this system.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
