    The Nature of the Far-Infrared Emission from Seyfert Galaxies
    Optical R-band imaging data and far-infrared (FIR) Infrared Space Observatory data from Seyfert galaxies are combined to show that the compact optical emission...
  • Publication
    The nature of the Kleinmann-Low nebula
    Recent data on, and interpretations of the Kleinmann-Low nebula are examined. It is suggested that associated high velocity gas is radiatively accelerated by a...
