We propose a high-resolution spectral and timing study of the emission andabsorption lines from the ultraluminous X-ray source (ULX) NGC 1313 X-1. With a750 ks XMM-Newton observation (split into three epochs), we will quantify thegeometry and physical properties of the relativistic wind and its relation withthe accretion rate and radiative luminosity, solving a fundamental problem ofblack hole accretion. We will determine: a) the launching radius of the wind; b)the mass outflow rate and kinetic power; c) the ionisation structure of theemitting plasma; d) the optical thickness of the wind as a function of spectralhardness of the X-ray continuum (a proxy for the viewing angle), which willdescribe the presence of orbital and super-orbital periods and the accretion power of ULXs.

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.
