| Abstract | We propose for exploratory observations of 13 low luminosity AGNs with candidateintermediate mass black holes (IMBHs). These objects were discovered in theSDSS. The optical line width-luminosity relation implies black hole masses ofthese AGNs in the range of 1e4-1e6 Msun. None of the 13 objects has beendetected in the RASS, and their X-ray nature has remained unexplored. These AGNsare expected to show most rapid X-ray variability and hottest accretion diskemission among all radio-quiet AGNs. They are the best candidates to study theeffect of a relatively low mass black hole. Our proposed observations willcharacterize their X-ray emission for the first time, extend their spectralenergy distributions and investigate the nature of IMBHs in galactic nuclei. |

| 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. |
