| Description | We propose two 20ksec long Target of Opportunity observations on a bright (more than 200mCrab) black hole transient in outburst, to study the relativistic Fe Kalpha line profile and its variability in such systems and to perform X-ray timing studies. Fe lines probe the innermost regions of accretion disks where the gravitational field is the most intense. To obtain a maximum signal to noise ratio in the line, these observations will be using the modified timing mode of the EPIC-pn cameras, recently employed successfully in observations of the relativistic line of Cygnus X-1. The accurate measurement of the line shape will then lead to constraints on the black hole spin. |

| 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. |
