Scientific paper

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.
