Description The study of quasi-periodic oscillations (QPOs) is of increasing importance in helping us to understand the enigmatic population of ultra-luminous X-ray sources (ULXs). Whilst few in number, these signals present an opportunity to understand the accretion flow and provide a diagnostic of the central, unknown mass by comparison of the joint spectral and timing characteristics of the emission to those of well studied X-ray binaries (XRBs) and active galactic nuclei (AGNs). We propose a single orbit observation of NGC 6946 X-1, providing only the second unambiguous high-quality dataset on a ULX with a QPO. This will allow the QPO and broad-band variability to be probed using the latest joint spectral-timing methods, allowing robust tests for models of the emission properties of this ULX.

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.
