|Title||The Broad-Band Spectral Shape of Fairall 9|
|Author||Ms Anne Lohfink|
|Description||We propose to observe the bare Seyfert 1 galaxy Fairall 9 for a net exposure time of 175 ks with both XMM and NuSTAR to study its broad-band spectral shape from the UV to the hard X-ray bands. This precise broad-band spectrum, will allow us to determine the continuum with high accuracy, enabling the removal of model degeneracies. In particular, we hope to identify the nature of the soft excess in the source and search for a high energy cut-off. Fairall~9 has been selected as a Priority A Target by the NuSTAR team, pre-approving the proposed NuSTAR observation.|

|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.
