  • Monitoring of active galactic nuclei. V. The Seyfert 1 galaxy Markarian 279
    We report on the Lovers of Active Galaxies' (LAG) monitoring of the Seyfert 1 galaxy Markarian 279 from January to June 1990. The source, which was in a very bright state, gradually weakened after the first month of monitoring: the Hα and Hβ flux decreased by 20% and 35% respectively, and the continuum under Hα by 30%. The luminosity-weighted

  • Intensive Spectroscopic Monitoring of NGC 5548 with HST, IUE, and Ground-Based Telescopes
    We present the results of a combined HST/IUE/ground-based spectroscopic monitoring campaign on the Seyfert 1 galaxy NGC 5548 that was undertaken in order to address questions that require both high temporal resolution (one day) and high signal-to-noise ratios. We find (1) that the ultraviolet and optical continuum variations are virtually

  • A high-resolution study of the structure of sunspot light bridges and abnormal granulation
    Strong light bridges (SLBs) represent an abrupt change in the physical conditions of sunspot umbrae. They divide the umbra into separate units (fragments, umbral cores) and very often show a granular structure. A photometric and spectroscopic study of SLBs, and also of abnormal granulation (AG) in a region of pores, is presented. Slit-jaw images

  • The inclination of network magnetic fields
    We have observed the linear polarization of 21 bright grains of the photospheric network close to the disk center. The linear polarization of Fe I 6302.5 A was always lower than 1.9 x 10-3 (referred to continuum intensity). This level of linear polarization implies a very small magnetic field inclination with respect to the vertical, which we

  • Surface photometry of low-luminosity radio galaxies
    We present the results on the optical morphology and structure of 25 low-luminosity radio galaxies. The radial dependence of parameters like the surface brightness, ellipticity, center, and position angle of the isophotes is presented to study the properties of the galaxies. Results for individual objects are discussed.
