|Title||THE HARD X-RAY SPECTRUM & VARIABILITY OF I ZW 1: ACCRETION PHYSICS & JET LAUNCHI|
|Author||Dr Daniel R. Wilkins|
|Description||We propose to conduct the first hard X-ray study of I Zwicky 1 (I Zw 1), a unique AGN that will yield great insight into the physical processes associated with accretion and the extreme environments around supermassive black holes. Rapid variability is seen in the X-ray emission as the corona evolves as well as complex, variable absorption from outflows. I Zw 1 is the first AGN in which there is evidence for distinct structures within the corona, including a core akin to the base of a jet. We propose to observe I Zw 1 for 250ks using NuSTAR, 130ks simultaneous with XMM-Newton. This will yield the most detailed, dynamic picture of how the corona is structured and how it evolves, transforming our understanding of how the corona and accretion disc drive AGN feedback.|

|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.
