Connection between the X-ray, UV and optical emission line regions of   AGNs
  In order to investigate the connection between the X-ray, UV and optical spectral line regions, we selected a sample of AGN which have the strong Fe K-alpha line and analyze the UV and optical spectral lines.   Here we present an example of AGN NGC 3516. In this object it seems that geometries of all three emitting regions are similar, i.e. the broad line shapes can be explained by the multicomponent emitting line region with a disk emission. The disk emission contributes to the wings, while one (spherical) emitting region contributes to the line core. Concerning the Fe K-alpha, UV and Balmer line shapes it seems that these broad line emitting regions in NGC 3516 are geometrically similar, i.e. in all wavelengths the lines are emitted partly from the disk partly from a spherical region.
