We propose a 130ks observation of the X-ray bright Seyfert 1.9 galaxy MCG-5-23-16 with XMM-Newton. Our present analysis of the short XMM observations ofMCG-5-23-16 reveals one the best known examples of a relativistically broadenediron K line, with the red-wing of the line extending down to 5keV in the EPICdata. Indeed MCG-5-23-16 is one of only a handful of objects that clearly show abroad iron line with XMM-Newton. Therefore it is imperative that we study theiron K line emission in this Seyfert galaxy in much greater detail. We alsopropose for a simultaneous 50ks Chandra/HETGS observation, to constrain thenarrow core of the line. These observations will not only confirm the existenceof the broad disk line, but also enable us to determine the accretion disk geometry.

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.
