    The complexity of the coronal line region in AGNs: Gas-jet interactions and outflows revealed by NIR spectroscopy
    Apart from the classical broad line region (BLR) at small core distances, and the extended classical narrow-line region (NLR), a subset of active galactic...

    The extended narrow line region of NGC 4151
    We present high quality long-slit spectra of the extended narrow line region (ENLR) near the nucleus of NGC 4151. We have used these data to map the spatial...

    The extended nebulosity in the radio galaxy 3C 227
    3C 227 (z = 0.085) exhibits one of the more spectacular extended nebulosities to be found among active galaxies at moderate redshifts. The gas can be traced to...

    The influence of relativistic kinematics on the asymmetry of spectral line profiles and the observed asymmetries in AGN's
    The influence of general relativistic effects on spectral line profiles is studied. Some peculiarities observed in the profiles of broad lines of AGNs, like the...
