| Description | We study a transient ultraluminous X-ray source (ULX) in M83, which went into outburst in 2010 and is now evolving towards the luminosity range of ordinary stellar-mass black holes. We propose an XMM-Newton and HST study: a) to model the spectral state evolution during the decline, and discover how the ULX regime is linked to the sub-Eddington accretion states of Galactic BHs; b) to determine or constrain the mass of the BH, from X-ray spectroscopy; c) to quantify the properties of the irradiated disk, and its response to variable X-ray illumination. |

| 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. |
