| Abstract: |
XMM-Newton observations of type I AGN with are presented. The properties of the iron K emission lines are reviewed, the majority of objects show narrow iron lines from cold matter that must originate far from the inner accretion disc, perhaps in the putative molecular torus. The strength of this narrow line decreases with luminosity, implying a reduction in the solid angle of the obscuring material - this may have implications for the occurance of type II quasars. To date, there are only a few examples of the broad iron K line with XMM-Newton, but in one case (MCG -6-30-15) the extreme breadth requires a Kerr metric for the central black hole. I will also discuss new X-ray spectral features, including two AGN where deep iron K-shell absorption is observed, suggesting that a high column of ionised matter exists along the line of sight, but close to the central engine. |
