We propose XMM observations of six AGNs from a unique sample of super-Eddingtonaccreting massive black hole(SEAMBH)candidates for which we have obtained directmeasurements of the broad line region size and black hole mass via reverberationmapping in Lijiang,China. Surprisingly, most objects of this type measured byus have broad line region sizes that are considerably smaller than those knownin the literature for lower Eddington ratio AGNs. Only half of the reverberationmapped SEAMBH AGNs have X-ray observations and our proposed observations willdouble the number.The new data will enable us to combine our optical data andSED with the X-ray spectrum and,perhaps,to probe the physics of slim accretiondisks that are thought to power most of the known high redshift AGNs.

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.
