Evolutionary models and recently reported infrared and X-ray signatures suggestthe presence of intermediate-mass black holes (IMBHs) in nearby dwarf galaxies(dGs). We propose to search for these objects with deep X-ray observations. Thepotential discovery of these X-ray sources will provide an extraordinaryopportunity to test evolutionary models driven largely by the internal dynamicsof centrally-located massive objects. The data will also be extremely useful inextending the MBH- sigma relation down to the mass scale of dGs.

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.
