|Title||MKN668 AND HIS BROTHERS: ARE THE AGN IN GPS GALAXIES OBSCURED?|
|Author||Dr MATTEO GUAINAZZI|
|Description||A recent XMM-Newton observation of Mrk668 has uncovered for the first time signatures of hot (Tvirgul10^7 K) gas in the X-ray spectrum of a GHz Peaked Spectrum radio source, together with the first evidence for a Compton-thick absorbed radio loud-AGN. We propose to observe during the XMM-Newton AO3 3 GPS radio galaxies detected by ROSAT, none of them ever observed in hard X-rays so far. We complement our request with 2 GPS radio galaxies detected by Chandra in snapshot (5 ks) observations, to obtain their first good quality X-ray spectrum. This program will more than double the number of GPS galaxies, for which hard X-ray measurements are available. The total requested allocation time for this program is 100 ks.|

|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.
