| Description | Optical observations of P13 in NGC 7793 allowed us to determine for the first time the mass of the black hole in an ULX, clearly indicating super-Eddington accretion. The donor is a B8I star in an eccentric orbit. Swift XRT monitoring revealed a likely eclipse as well as an extended faint state. Our serendipitous faint state Chandra spectrum shows evidence of redshifted iron line which we tentatively assign to a jet. We propose to obtain high S/N spectra of the bright, faint and eclipse states. Spectral properties of the bright state will define the key signatures of super-critical accretion. Eclipse observation will allow us to constrain the orbit and to possibly reveal evidence of bulk motion. Faint state observations will likely provide the first direct detection of a jet in an 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. |
