Description Hyperluminous X-ray sources (HLXs) with X-ray luminosities above 1e42 erg-s are very likely the long-sought intermediate-mass black holes (IMBHs) of 1e2- 1e5 solar masses, as demonstrated by the recent intensive studies of HLX-1 (Farrell et al. 2009), the only HLX known so far. To better study the HLX-IMBH populations, we have searched for new HLXs across the whole sky with the ROSAT All Sky Survey (RASS), yielding a sample of 10 new HLXs. Here we request 150 ks to observe five HLXs with XMM-EPIC to determine the fine spectral features and associated accretion states, and to study the correlated spectral and timing properties in hope to estimate the black hole masses.

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.
