| Abstract | The growth of early supermassive black holes requires high accretion ratereleasing huge amount of radiation and winds slowing down both accretion ratesand start formation. This programme focuses on the physics of high-massaccretion on the stellar mass level where super-Eddington luminosities are morecommonly observed. We propose deep X-ray observations of the corner stonesupersoft Ultra-Luminous X-ray source (ULX) NGC 247 X-1 to probe the very softend of the hardness distribution necessary to complete the current view. This isthe only source that continuously switches between supersoft and classicalultraluminous states, providing a unique workbench for our study. With a 1 MsXMM-Newton program, we will detect ultrafast outflows and understand how super-Eddington accretion works. |

| 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. |
