| Description | We request XMM observations of the nucleus of the radio galaxy Cen A to study the time variability of its broadband spectral energy distribution (SED) in order to test and constrain jet emission models of radio-loud active galactic nuclei. Due to Cen A.s proximity, the jet emission and formation mechanism can be investigated in unique detail providing essential information on AGN physics in general. Although being a frequently observed source, no time-dependent, simultaneous SEDs covering the whole spectrum from radio to gamma-rays have been obtained for CenvirgulA so far. Since AGN are highly variable sources, only contemporaneous SEDs covering the typical variability timescale of hours to months allow us to constrain parameters of jet emission models. |

| 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. |
