Description We propose a 100 ks observation of NGC424 to exploit the full range of XMM-Newton capabilities (RGS+EPIC) by studying the properties of the different materials found in the nucleus of this object.NGC424 is one of the brightest Compton-thick AGN,thus being one of the few sources which presently permit this kind of analysis.The proposed 100 ks EPIC spectrum will allow us to study in detail the properties of the torus,by measuring:the iron Kalpha-Kbeta ratio and the iron Kalpha centroid energy,to determine its ionization state and then estimate its distance from the Black Hole;the Compton Shoulder,to check if the cold reflecting matter is indeed the inner wall of the obscuring torus.On the other hand, the RGS high resolution spectrum will allow us to take advantage of

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.
