Spectral Properties of Blazars Observed at Ultraviolet and X-Ray Frequenciesare flatter than average in all bands. The average X-ray luminosity of the whole sample and that of the X-ray selected group are the same. It is suggested that relativistic beaming may enhance the radio but not the X-ray emission of radio selected blazars.

Discovery of Narrow and Variable Lines in the Ultraviolet Spectrum of the Seyfert Galaxy NGC 4151, afications for these lines, for example with transitions excited by fluorescence, have been found. An attractive — but speculative — possibility is that the regions emitting them are associated with a two-sided jet reminiscent of SS 433.

Evolutionary Continuity of the Optical AGNsized in terms of quantities of direct astrophysical meaning. Specific issues here discussed are: the continuity between Seyfert 1 nuclei and QSOs; a first parameterization of the interactions as triggers of activity; the rise of the QSOs; the evolutionary peculiarity of BL Lac Objects.

Continuity in the Observed Properties of QSOs, High-Redshift Emission-Line Radio Galaxies, BL Lac Obat the continuity argument is compatible with many of the observations, provided (i) that the idea of directed bulk relativistic motions in many objects which show apparent superlight velocities or very large rapid flux variations is accepted, and (ii) that all of the evidence for the physical assoc

Spectral Properties of Blazars Observed at Ultraviolet and X-Ray Frequenciesments close in time and corrected for contamination from the surrounding galaxy. It is found that the overall spectrum of this class of objects steepens substantially between radio and infrared and between infrared and ultraviolet frequencies but not between ultraviolet and X-ray frequencies. The sp
