Abstract	It has been suggested that ULXs are in a new super-Eddington ultraluminousaccretion state, and that they progress through a sequence of three spectralregimes with increasing accretion rate. However, our recent results (Sutton etal. 2013) indicate that inclination is also critical in determining the observedX-ray properties. These properties can broadly be explained by a massiveradiatively-driven wind that emerges as the Eddington limit is exceeded, andforms a funnel around the black hole axis. Previous observations show NGC 5204X-1 straddling the boundary between two ultraluminous regimes, marking it as acritical source in testing this scenario. Here we propose to obtain a furtherfour 20 ks XMM-Newton EPIC observations, which will allow us to probe the validity of the proposed model.

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.
