|Title||The connection between the X-ray corona and the nuclear radio emission in AGN|
|Author||Dr Claudio Ricci|
|Description||We propose here the first joint study of the mm-X-ray variability of a radio-quiet AGN, using XMM-Newton and ALMA to monitor the brightest unobscured AGN in the southern sky, IC 4329A, observing it once per day over ten consecutive days. The ALMA monitoring has already been approved (priority A, highest resolution). This would be the first time such a monitoring is carried out, and the detection of correlated mm-X-ray variability would be a crucial proof of the coronal origin of the nuclear radio emission in radio-quiet AGN. Besides, this would also be fundamental to understand the origin of the X-ray emission, proving, for the first time, that the X-ray corona is magnetically-heated.|

|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.
