Description Ultra-Luminous X-ray sources (ULXs) may represent 30-100 solar-mass accreting black holes -- extremely important if true, but highly controversial. We propose here multiple XMM-Newton observations of the nearby spiral galaxy ICvirgul342, which harbors two of the most luminous and best studied ULXs, in order to characterize how the ULX spectra evolve as a function of luminosity. Comparing this with the behavior of the stellar mass accreting black holes in our Galaxy will establish (or refute) the high mass black hole scenario for ULX.

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.
