  Title: SEARCH FOR DOUBLE-PEAKED EMISSION LINES IN BROAD-LINE RADIO GALAXIES            


Abstract:
 We propose to continue our search for resolved Fe K lines in broad-line radio
 galaxies. The inner accretion-disk structure of BLRGs might be different from that
 of Seyfert galaxies, and Fe K line profiles could constitute important evidence of
 those differences. We will be able to resolve emission-line components that
 correspond to the double-peaked Balmer lines that recently appeared in Pictor A, and
 separate them from any zero-velocity line that might also be present. Plausible
 interpretations of double-peaked lines include fluorescence from an accretion disk,
 and bipolar flows associated with radio jets. The relative strengths of the Fe K and
 Balmer lines can be used to estimate the column density and covering factor of
 emitting material, which can help to distinguish among models.
