We present results from a simultaneous Chandra HETG and XMM-Newtonobservation of NGC 3516. We find evidence for several narrow components of FeKalpha along with a broad line. We consider the possibility that the linesarise in an blob of material ejected from the nucleus with velocity ~0.25c. Wealso consider an origin in a neutral accretion disk, suffering enhancedillumination at 35 and 175 gravitational radii, perhaps due to magneticreconnection. The presence of these narrow features indicates there is noComptonizing region along the line-of-sight to the nucleus. This in turn iscompelling support for the hypothesis that broad Fe Kalpha components are, ingeneral, produced by strong gravity.Comment: 12 pages, 3 color figures. LaTeX with postscript figures.
