Description We propose XMM observations of six AGNs from a unique sample of super-Eddington accreting massive black hole(SEAMBH)candidates for which we have obtained direct measurements of the broad line region size and black hole mass via reverberation mapping in Lijiang,China. Surprisingly, most objects of this type measured by us have broad line region sizes that are considerably smaller than those known in the literature for lower Eddington ratio AGNs. Only half of the reverberation mapped SEAMBH AGNs have X-ray observations and our proposed observations will double the number.The new data will enable us to combine our optical data and SED with the X-ray spectrum and,perhaps,to probe the physics of slim accretion disks that are thought to power most of the known high redshift AGNs.

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.
