| Abstract | A small sample of nearby Compact Symmetric Objects (CSO) has been monitored inthe radio band allowing for measurements of the kinematic age and indicatingthat they may be very young (<3000 years). X-ray observations of these CSOsuggest that the X-ray obscured CSO have smaller radio structures than the X-rayunobscured CSO with the same 5 GHz radio power. We propose to obtain highquality X-ray spectra of two Compton Thick CSO candidates in order to verifytheir Compton thick nature and thus (1) confirm that some radio sources are bornin a complex environment with high density cold clouds impacting the sourceearly expansion, (2) support the idea that the radio jets decelerate byinteractions with these 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. |
