Title The intriguing Fe-line profile in Seyfert 1 nuclei: expanding the XMM-N census

Description We propose to obtain high signal to noise EPIC spectra of a sample of X-ray bright Seyfert 1 galaxies. The main objective is to properly characterize the profile of the iron fluorescence line. Hence, the sample of Seyfert 1 galaxies with proper measurements of the iron line width will be increased and current (contradictory) models for its origin will be probed. The relatively long exposure times needed will also allow good signal to noise RGS spectra to characterize the soft X-ray emission and measure possible emission-absorption lines from photoionised gas in the vicinity of the nucleus. Rapid variability, when detected, will be used to constrain sizes and causality effects between the different emitting-absorbing regions.

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.
