| Abstract | We propose an observation of Mrk 6, a bright Seyfert 1.5 galaxy with complex andvariable permitted lines, an ionization cone, and remarkable radio structures.Our ASCA study of Mrk 6 revealed intrinsic X-ray absorption and a broad ironline, and XMM will study these in much greater detail. The X-ray absorptionprobably arises in a torus atmosphere, and we will constrain the geometry andionization properties of the absorber to test this hypothesis. We will model anyabsorption variability, and we plan simultaneous HST STIS UV spectroscopy forcoordinated UV/X-ray modeling. Fitting the iron line will determine theinclination of the inner accretion disk. Such fitting is particularly importantfor Mrk 6 because there are independent indications of an edge-on orientation. |

| 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. |
