|Title||XMM-NEWTON SPECTROSCOPY OF RX J1343.4+0001: A RADIO-QUIET TYPE II QSO AT Z|
|Author||Dr ENRICO PICONCELLI|
|Description||To date RX J1343.4+0001 (F(0.5-10) virgul 2 x 10e(-13) erg-cm2-s) appears the best candidate to unambiguously confirm the existence of radio-quiet X-ray obscured type II QSOs at high redshifts. By the 35 ks observation proposed here we will be able to definitively disentangle between the two hypothesis suggested on the basis of previous less sensitive ROSAT and ASCA measurements, i.e. a truly flat spectrum (very unusual for a radio-quiet QSO) or a highly absorbed object. The main goal of this proposal is to obtain the first high-quality X-ray spectrum of a member of this elusive class of high luminosity obscured sources whose existence is required in the synthesis models of the cosmic 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.
