|Title||Revealing Compton-thick luminous AGNs in powerful [OIII] emitters|
|Author||Dr Enrico Piconcelli|
|Description||We propose to complete an observing program accepted during the last AO aimed at discovering unquestionable examples of still-elusive, Compton-thick (CT) quasars among the most [OIII] luminous AGNs in the local Universe. We request XMM-Newton observations of two narrow line AGNs at z <0.04. The very large [OIII] luminosity of both sources points out an intrinsic X-ray luminosity typical of quasars, while previous low-quality X-ray data provided strong, although inconclusive, evidence of a reflection dominated spectrum. As demonstrated by the observation of the AO8 accepted target, that has successfully revealed a CT quasar, our observing strategy is designed to minimize the risks of ambiguous results that have affected most of blind searches for CT luminous AGNs performed so far.|

|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.
