| Description | We propose a joint 6x30 ks Chandra and 6x40 ks XMM-Newton monitoring campaign of the lens system RXJ1131 to reach the following goals: (1) Confirm and validate the microlensing method of constraining the spin and inclination angle of a z=0.658 lensed quasar. (2) Identify the origin of the soft excess, and (3) compare these results to those obtained by employing the relativistic Fe line method. The Chandra observations are crucial in resolving the 4 images, unambiguously identifying a microlensing event, and providing the unlensed source spectrum. XMM-Newton has the required effective area to provide constraints on the soft and hard reflection components originating from the disk. |

| 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. |
