| Abstract | Recent advances have shown X-ray flux to be simply correlated withreflection-signatures from the disk and an associated wind. It appears twothings are essential to observe the disk/wind: 1) catch the Seyfert in ahigh-state where disk/wind features show up strongly and 2) separate outreprocessing from distant gas to allow isolation of disk/wind features. NGC 3516provides the ideal source for further study in this regard. The source iscurrently in a very high state, which we predict will lead to observablefeatures from the disk and its wind. We request 210 ks XMM exposure on NGC 3156with supporting Chandra time to test our prediction of flux-linked diskreflection and wind. |

| 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. |
