Description NGC 5907 ULX-1 is the most luminous of the 3 ULXs known to be accreting pulsars. At 17.1 Mpc, its X-ray isotropic luminosity peaks at 1e41 erg-s, 500 times the Eddington limit for a NS. Understanding the physics of this extreme object, for a long time prototypical of IMBHs, which defeats simple theoretical explanations, is interesting per se and essential for population studies and searches for pulsation in other ULXs. The most effective strategy is to repeatedly observe it with XMM and NuSTAR with a carefully devised schedule. Their synergy will provide us also with orbital- and spin-phase-resolved broad-band X-ray spectroscopy, essential for a better understanding of this object, in the context of other extreme 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.
