| Abstract | Hyperluminous X-ray sources (HLXs) with X-ray luminosities above 1e42 erg/s arevery likely the long-sought intermediate-mass black holes (IMBHs) of 1e2- 1e5solar masses, as demonstrated by the recent intensive studies of HLX-1 (Farrellet al. 2009), the only HLX known so far. To better study the HLX/IMBHpopulations, we have searched for new HLXs across the whole sky with the ROSATAll Sky Survey (RASS), yielding a sample of 10 new HLXs. Here we request 150 ksto observe five HLXs with XMM/EPIC to determine the fine spectral features andassociated accretion states, and to study the correlated spectral and timingproperties in hope to estimate the black hole masses. |

| 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. |
