| Description | We propose to observe the Galactic Microquasars 1E1740.7-2942 and GRS 1758-258 in their standard low-hard state. The aim of this proposal is to search for the ultrasoft component recently detected in GRS 1758-258. Its presence could argue in favor of the two component accretion flow models recently invoked for accretion in Black Hole binary systems. We plan to use these data in conjunction with the data obtained from the INTEGRAL Galacic Plane and Galactic Center Deep Exposure Core program observation in order to measure the high energy Comptonised spectrum in the gamma-ray domain. We will have access to these data as members of this team are IBIS/INTEGRAL CoIs. A total of 20 ksec is requested for this project. A total of 20 ksec is requested for this project. |

| 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. |
