  • The complex narrow-line region in NGC 4151
    New narrow-band images of NGC 4151, taken in excellent seeing conditions with the 4.2-m William Herschel Telescope are presented. These reveal a wealth of detail that can be used to test models for the anisotropy of the narrow-line region. From forbidden O III (4959, 5007)/H-alpha line ratio map, three important features are identified: (1) a jet

  • The bright X ray transient GS2023+338 (=V404 Cyg) in optical outburst and decline
    The results of optical spectroscopy and photometry from La Palma (Canary Islands) of V404 Cyg are presented. They correspond to the optical counterpart of the new X-ray transient GS2023+338 discovered by Ginga. The overall light curve is similar to that of the previous optical outburst of this object, recorded as Nova Cyg 1938 and classified as a

  • Extended line emission in AGN: looking at the central engine.
    Regions of high excitation gas were detected around various active galactic nuclei. Their shape resembles a cone whose axis is oriented close to the radio axis. The radiation emitted by the nucleus may be responsible for the high ionization of the line emitting gas. Moreover there is evidence that the radiation field should be anisotropic and
