| Abstract | We propose to perform a simultaneous observation with XMM-Newton (130 ks) andNuSTAR (75 ks) of the lensed quasar RX J1131-1231. The flux magnification makesit possible to study in detail the central regions of a quasar at moderateredshift (z=0.658). The existing X-ray data reveal the presence of strongreflection features in RX J1131-1231, suggesting a rapid rotation of the centralblack hole. The new broadband observations proposed here will probe for thefirst time the hard X-ray emission of the source, allowing us to witness thebehaviour of the broadband X-ray spectrum in response to the frequentmicrolensing events. RX J1131-1231 provides the unique opportunity of measuringthe spin of the black hole employing two independent methods: reflection and microlensing. |

| 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. |
