|Title||A long X-ray look at the accretion disk in NGC 2992|
|Author||Dr Andrea Marinucci|
|Description||We propose a ToO observation of the highly variable Seyfert galaxy NGC 2992 with XMM-Newton for 250 ks. The pointing will be triggered by Swift-XRT to catch the source during its bright flux state. Even though the source has been extensively observed by all major X-ray satellites, its high flux state is still poorly studied. The time behavior of the iron line is very interesting, suggesting the presence of a relativistic component which becomes more extreme at high flux levels. In addition, an outflow component has been found in the recent NuSTAR spectrum and confirmed by a re-analysis of the 2003 XMM observation. We aim at investigating the spectral evolution of the accretion disk features in the high state, on a time scale of a few hours.|

|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.
