Abstract	We propose joint observations with NuSTAR and XMM-Newton of the M51 galaxiesthat will provide the best simultaneous, high-time resolution, and sensitivebroadband X-ray spectral dataset on the sources within them yet. The jointdataset will yield the first high-quality broadband spectrum of at least oneneutron-star-powered ultraluminous X-ray source in the galaxy, possibly two.This will allow a detailed spectral decomposition and sensitive searchesfor cyclotron lines. The timing resolution of XMM-Newton will allow us todetect pulsations, yielding an improved orbital solution for one ULX, andperhaps detecting them for the first time in one of the many others in thegalaxies.

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.
