    Steps toward Determination of the Size and Structure of the Broad-Line Region in Active Galactic Nuclei. XI. Intensive Monitoring of the Ultraviolet Spectrum of NGC 7469
    From 1996 June 10 to July 29, the International Ultraviolet Explorer monitored the Seyfert 1 galaxy NGC 7469 continuously in an attempt to measure time delays between the continuum and emission-line fluxes. From the time delays, one can estimate the size of the region dominating the production of the UV emission lines in this source. We find the

    Stellar and Ionized-Gas Kinematics of the Seyfert 1 Galaxy NGC 3516
    We present bidimensional spectroscopy of the central region (9."4 x 12."2) of the Seyfert galaxy NGC 3516 in the two spectral ranges 4186-5839 A and 6110-7890 A. The data (95 x 2 spectra) were simultaneously obtained with an optical fibre system (2D-FIS). The two-dimensional velocity map of the stellar component was obtained from the Mg I b

    Resolved Structure in the Nuclear Region of the Ultraluminous Infrared Galaxy MRK 273
    We have studied the core morphology of the ultraluminous infrared galaxy Mrk 273 by combining a high-resolution adaptive optics near-infrared image with an optical image from the Hubble Space Telescope and interferometric radio continuum data, all at spatial resolutions of 150 mas or better. The near-infrared image reveals that the nucleus has two

    On the wind momentum problem of O-type stars in the galaxy
    We have examined the wind momentum problem of O-type stars in the Galaxy. It is shown that the discrepancy between theoretical and empirical mass loss rates and terminal velocities can be reversed by using recently updated values of force multiplier parameters. With these new values, the momentum problem found by former investigators is reversed so

    OBSERVACIONES DE ALTA RESOLUCION ESPACIAL DE LA RADIO GALAXIA CYGNUS A
    Como se justifica en la memoria, Cygnus A es una de las radiogalaxias más interesantes y que más influencia han tenido, históricamente, en el estudio de la actividad. En este trabajo se presentan y combinan fotometría de alta resolución espacial y espectroscopía de rendija larga en varias posiciones asociadas a los conos de radiación para estudiar

    Multiple collimated outflows in a planetary nebula?
    We present high resolution images and high dispersion spectra of the planetary nebula IC 4593. Benefiting from superb seeing (0″.4), the narrowband images reveal the existence of a complex system of collimated knots in the inner 15″ of the nebula.The knots, which morphologically resemble outward facing bow-shocks, are located at different position
