Description The new X-ray observatories have given us great insights into the energetic
accretion processes in active galaxies, providing important clues about possible
connections between different classes of radio-quiet and radio-loud AGN.
Although much of the current work is focused on parameterizing the X-ray
emission of AGN, virtually nothing is known about the possible evolution of the
X-ray properties over the lifetime of an AGN. We propose to perform the first
X-ray observations of the 5 most famous and extensively studied young GPS radio
galaxies in the sky. This will yield important information on the evolution of
the accretion flow over the AGN-lifecycle, and the mass and distribution of
circumnuclear material around young radio sources.

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.
