Title Towards Understanding Ultraluminous X-ray Sources in Nearby Galaxies


DOI 10.5270/esa-dp5d79e
Author Dr Manfred Pakull
Description One of the unsolved questions in contemporary astrophysics is the nature of the bright non-nuclear X-ray sources which appear to surpass by large margins the Eddington luminosity of a "stellar-mass" compact object. We have recently discovered extended emission nebulae around several ultraluminous sources (ULX) in nearby galaxies which are partly photoionized by their XUV radiation; extent and expansion velocity suggest that these ULX were formed in energetic events some 1E6 years ago. Here we propose to observe a sample of bright ULX in nearby galaxies with the goal to understand their X-ray spectra and to test current ideas of accretion physics in 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.
