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.
