Abstract | Ultra-Luminous X-ray sources (ULXs) may represent 30-100 solar-mass accretingblack holes -- extremely important if true, but highly controversial. We proposehere multiple XMM-Newton observations of the nearby spiral galaxy IC~342, whichharbors two of the most luminous and best studied ULXs, in order to characterizehow the ULX spectra evolve as a function of luminosity. Comparing this with thebehavior 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 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. |
