| Abstract | We propose joint NuSTAR (200 ks) and XMM (60 ks) observations of a nearby (30Mpc) hyper-luminous X-ray source (HLX) to characterize, for the first time, itsbroad-band spectrum, which we will use to distinguish between scenarios wherethe extreme luminosity is due to sub-Eddington accretion onto an intermediatemass black hole, or super-Eddington accretion onto a stellar mass compactobject. This study will extend the power of broad-band spectral characterizationwith NuSTAR to understanding the accretion state in the HLX luminosity regime. |

| 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. |
