Description We propose a 100ksec XMM-EPIC observation of one of the brightest nearby ULX, which resides in the galaxy Holmberg II (UGC 4305). This observation will allow us to measure the shape of the fluctuation power density spectrum (PDS) for this source. Comparison of the measured PDS shape and break-frequency with those obtained from stellar-mass galactic black hole binary systems and AGN, will allow us to determine unambiguously whether this ULX is simply a high luminosity extra-galactic analogue of galactic black hole binary systems, but with anisotropic X-ray emission, or more intriguingly the first known representative of the so-called ''missing class.. of intermediate-mass black holes, with a mass in the range 100 - 10000 solar 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.
