So far there is only one AGN, Ark 564, whose power spectral density (PSD) showsa multi-Lorentzian shape which is similar to that seen in BHBs emitting in the.very high state. Recently we discovered that the PSD of the NLS1 RXJ1140.1+0307, which is claimed to harbor an intermediate mass black hole with asuper-Eddington accretion rate, also appears to have more than one Lorentziancomponent. However, the previous XMM observation is too short to extend the PSDto lower frequency. Therefore we propose a long (120 ks) XMM-Newton observationof RX J1140.1+0307, in order to perform a deep investigation of its PSD, alongwith other variability properties. Because such phenomenon observed in the PSDof AGN are extremely rare, it is important to study the best examples in detail.

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.
