Assigned ID: 25 ----- Submission 1 (Mon Jan 17 21:07:48 GMT 2005) ----- Institution of Co-I Rokaki not available in list We propose to determine the gross structure and flow of the broad emission line region (BELR) of radio-loud active galactic nuclei (AGN). Our approach is to look at the change of emission line properties (such as, e.g., FWHM and equivalent width) with inclination angle, the latter determined by a new VLBI/X-ray technique. This will extend the work of Rokaki, Lawrence, et al. by including both low- and high-ionization broad emission lines. We will use 197 HST archival spectra for 25 AGN covering multiple broad emission lines of varying ionization (and so radius). We shall be able to distinguish rotation about the radio axis, outflow and turbulent motions within the BELR. The result will be more accurate black hole masses at low and high redshifts and a deeper understanding of AGN dynamics.
