|Title||EVOLUTION OF THE X-RAY PROPERTIES OVER THE LIFETIMES OF RADIO-LOUD AGN|
|Author||Dr IGNAS SNELLEN|
|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.
