    The O III narrow line shapes in spectra of Mrk 817.
    The O III (4959, 5007) lines from spectra of Mrk 817 obtained from a 9-year long period were analyzed. A blue asymmetry of the lines is noticeable. The authors...

    The radio source and bipolar nebulosity in the Seyfert galaxy NGC 3516
    Results of radio continuum and optical emission-line observations of the type 1 Seyfert galaxy NGC 3516 are presented. The radio maps reveal an elongated one...

    The response of the broad emission line region to ionizing continuum variations
    The variability of the broad emission lines in Seyfert galaxies is naturally explained in terms of photo-ionization models of the broad line region (BLR) as the...

    Variability of NGC 5543: The continuum
    Simultaneous UV and optical variations of NGC 5548 suggest a common origin of the continuum flux at both ranges. If the bulk of the UV flux had a black body...

    Variability of NGC 5548: The lines
    Two broad components in the strongest UV emission lines of NGC 5548 are identified. The components respond differently to continuum changes. A normal broad...
