Description The nature of ultraluminous X-ray sources (ULXs) remains controversial. We do not know whether they host stellar- or intermediate-mass black holes, nor do we have a clear understanding of the accretion process. Similarly poorly studied is the accretion onto supermassive black holes in low-luminosity active galactic nuclei (LLAGN). To address these problems, sensitive observations at energies above 10 keV are needed. We propose to observe with INTEGRAL for a total exposure of 4 Msec (2 Msec in AO7 + 2 Msec in AO8) a unique sky region where two of the brightest ULXs, M82 X-1 and Holmberg IX X-1, and one of the brightest LLAGN, M81, are located.

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.
