| Abstract | The physical origin of the radio emission of Radio-Quiet AGN remains broadlyunclear. The observation of flat/inverted radio spectra at GHz frequenciessupport the presence of an unresolved synchrotron self-absorbed region close tothe supermassive black hole. If true its size should be of the order of theX-ray corona size when observed in the millimetric (mm) domain. Simultaneousfast X-ray and mm variabilities are then expected. We propose to observe asample of RQ AGN simultaneously in X-ray and mm. Whether the fast variability isdetected or not, it will in any case put strong physical constraints on theemitting plasma. The XMM and NOEMA call being not phased, this XMM proposal isthe first step of the project. It will be followed by the submission of a NOEMA proposal. |

| 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. |
