Description The galaxy M82 harbors two notable ultraluminous X-ray sources (ULX): M82 X-2, the archetipal pulsating ultraluminous X-ray source (PULX), and M82 X-1, a IMBH candidate. The extreme luminosity of ULXs, and the observation of strong winds from these sources, suggests that these sources are undergoing strongly super-Eddington accretion. The supply of matter that powers these accreting systems is likely to come from Roche Lobe overflow from a more massive companion star, and should produce changes of orbital period observable in time scales of virgulyears. This program aims at detecting this orbital period derivative through pulsar timing in M82 X-2, and study in detail the quasi-periodic oscillations from both ULXs.

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.
