| Abstract | We propose to use {it XMM} to perform X-ray spectroscopy on the nucleiof several nearby galaxies which harbor low-luminosity active galacticnuclei (LLAGN; NGC 4736, NGC 5033, and NGC 1052). {it ASCA}observations of these and other LLAGN suggest iron emission-lineproperties quite different from those of luminous Seyfert galaxies.{it XMM} will provide definitive measurements of the iron line propertiesin these systems (physical line width, equivalent width, centroidenergy). This has important implications for the physics of accretionin LLAGN. |

| 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. |
