Are compact radio galaxies intrinsically X-ray weak? Do they otherwise live indense environments? If the latter is true, does the nuclear gas affect the jetevolution in radio-loud Active Galactic Nuclei (AGN)? In order to answer thesequestions, we propose to complete within the XMM-Newton AO6 a radio-selectedcomplete sample of Giga-Hertz Peaked (GPS) galaxies. We request 7 objects, for atotal allocation time of 170 ks. The proposed observations will provide clues onthe nature of compact radio sources, and on the ultimate fate of small-scaleradio structure evolution.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
