Abstract Intermediate mass black hole (IMBH) are important in studies of black hole andAGN physics and cosmology, but little is known about IMBH as a population due totheir rarity, especially in the X-ray band. We propose to observe with XMM awell defined, volume limited, nearest (within 250Mpc) sample of IMBH AGN withthe least nominal black hole masses known so far (<3 10^5 M_sun) estimated usingthe linewidth-luminosity-mass relation, which are discovered in our recent work.XMM will enable detailed studies of X-ray spectral and temporal properties forsuch objects both individually and as a sample extending up to 10keV energyrange, and will double the size of IMBH AGN with X-ray spectra to about twodozens.

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.
