Abstract We propose a 50 ks XMM-Newton observation of the X-ray luminous, Type 1 QSO FTMJ0830+3785 (z=0.413). We aim at obtaining the first high-quality spectrum ofthis recently-discovered 2MASS QSO to assess its peculiar X-ray spectralproperties. A very short 9 ks Chandra observation has revealed the statisticallysignificant presence of puzzling emission/absorption line-like features atenergies which do not correspond to any obvious rest-frame atomic transition.Similar features are observed in the spectra of a handful of intensively-studiedSeyferts and attributed to relativistically-moving material surrounding thenuclear X-ray source, but have never been seen in the spectra of members of thepoorly-studied, high luminosity (LX >10e45 erg/s) dust-reddened QSO population.

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.
