| Abstract | Ultraluminous X-ray sources (ULXs) are extragalactic X-ray sources possiblyhosting super-Eddington accreting black holes or neutron stars. The ULXpopulation shows sources with randomic long and short-term variability. Weselected the twelve nearby (<20 Mpc) galaxies that most probably host ULXs andthat were not observed in X-rays. We ask for snapshot (10 ks) observations tocomplete the census of ULXs in the nearby universe. |

| 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. |
