Author European Space Agency
Description The space density of the most powerful absorbed AGN (QSO2) and their
contribution to the AGN luminosity output remains uncertain. Many of these
objects are severely attenuated, so hard X-ray surveys alone do not fully prove
the bulk of the obscured QSO population in the nearby Universe. We propose a 80
ksec XMM-Newton observation of an optically selected QSO2 at zvirgul0.1. Comparing
its [OIII] and 2-10 keV luminosities the source is likely a Compton-thick AGN.
However, the X-ray spectral analysis seems to indicate that it might be instead
Compton thin and X-ray weak. The proposed observations will allow us to unveil
the true nature of this source and will give us key information on whether
objects such as this are intrinsically different to the QSO2 population detected in hard X-ray surveys.

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.
