| Abstract | Low-mass black hole (LMBH) with masses of < 10^6 M_sun are important in studiesof black hole physics and cosmology, but little is known about LMBH as apopulation due to their rarity, especially in the X-ray band. We propose toobserve with XMM a well defined, X-ray bright sample of AGN with the low blackhole masses estimated from the virial method, which are discovered in our recentwork. XMM will enable detailed studies of X-ray spectral and temporal propertiesfor such objects both individually and as a sample extending up to 10keV energyrange, and will double the size of LMBH AGN with high S/N X-ray spectra to abouttwo dozens. |

| 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. |
