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.
