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

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.
