| Abstract | Following a series of remarkable recent discoveries, we now know thatsome of the most luminous members of the ultraluminous X-ray source(ULX) population are actually powered by highly super-Eddington pulsars(i.e. neutron stars), making them the most extreme sustained accretorsknown. Six such systems are now known, but NGC5907 ULX1 stands out asthe most luminous, peaking at Lx ~ 1e41 erg/s. Here we propose a pair ofsimultaneous NuSTAR+XMM observations of NGC5907 ULX1. These will allowus to continue to track the long-term evolution of the neutron star spin,help investigate why the pulsations are transient in some ULX pulsars, andexplore the nature of the long-term 78d X-ray period present in this system. |

| 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. |
