| Abstract | We request XMM observations of the nucleus of the radio galaxy Cen A to studythe time variability of its broadband spectral energy distribution (SED) inorder to test and constrain jet emission models of radio-loud active galacticnuclei. Due to Cen As proximity, the jet emission and formation mechanism canbe investigated in unique detail providing essential information on AGN physicsin general. Although being a frequently observed source, no time-dependent,simultaneous SEDs covering the whole spectrum from radio to gamma-rays have beenobtained for Cen~A so far. Since AGN are highly variable sources, onlycontemporaneous SEDs covering the typical variability timescale of hours tomonths allow us to constrain parameters of jet emission models. |

| 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. |
