| Abstract | A small sample of nearby Compact Symmetric Objects has been monitored in radioto measure the kinematic ages. These sources are young (<3000 years). RecentX-ray observations suggest that their Compton thick fraction may be relativelyhigh compared to a sample of nearby AGN. We propose to obtain high quality X-rayspectra of Compton thick CSO candidates in order to verify their Compton thicknature. This would (1) establish that the fraction of highly obscured AGN ishigh (40%) in the youngest radio sources, (2) test the model in which radiosources are born in a complex environment with dense clouds impacting the sourceearly expansion,(3) imply that the radio jet decelerates by interactions withthese clouds, generates shocks and heats the central ISM contributing to the feedback process. |

| 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. |
