Description Black holes are seen over a huge range in mass in the Universe, ranging from stellar-mass black holes in binary systems, to supermassive (1E6 - 1E9 M(sun)) black holes at the centers of AGN. The recent discovery of low luminosity AGN with black hole masses less than 1E6 M(sun) allows a unique probe of the properties of accretion onto intermediate mass black holes. Only 6 of these objects have had previous significant X-ray observations, and have shown tantalising evidence of extreme variability and even a soft excess. Here, we propose to survey the 8 remaining objects with a mass less than 1E6 M(sun) and known X-ray counterpart, more than doubling the sample of good X-ray observations of these objects.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
