Description APM 08279+5255 is an exceptionally luminous BAL QSO, and although significantly lensed may be the most luminous object known in the Universe. Despite its bright infrared and optical magnitude it has not been seen in the ROSAT All-Sky survey, indicating a substantial amount of intrinsic absorption at the source rest frame. Here we propose 15 ksec EPIC observations in order to determine the column density, redshift and iron abundance of the absorber. This object may be an important missing link in our understanding of the X-ray background.

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.
