| Description | The 70ks XMM-Newton observation of the X-ray weak quasars PG 2112+059 in low state shows an X-ray spectrum with characteristics not reported so far for any other AGN. The quasar not only shows an extremely strong relativistic broad iron line, the whole spectrum can be understood as relativistically blurred reflection from a rotating inner disk around a supermassive Kerr black hole, whereas the usual power-law continuum is completely suppressed. We propose to monitor PG 2112+059 with two 70ks observations separated by half a year and, if the low state is detected, to study the detailed properties of the broad iron line with a (triggered) 220ks observations. |

| 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. |
