  • Modeling of integrated sunlight velocity measurements: The effect of surface darkening by magnetic fields
    It has been known since the work by Claverie et al. (1982) that integrated-sunlight velocities measured with the resonance scattering technique show variations with time scales of weeks to months. The cause can be understood in terms of the effects of solar activity as was pointed out by Edmunds & Gough (1983) and Andersen & Maltby (1983). The

  • Long-Slit Kinematic Data for a Sample of Interacting Ellipticals: Searching for `U'
    We have analyzed long-slit spectroscopic data for a sample of tidally disturbed elliptical galaxies. Rotation curves and velocity dispersion profiles have been measured at a variety of position angles in these galaxies and have been used to analyze the dynamical response and internal kinematics of stellar systems involved in strong gravitational

  • Interstellar and intergalactic gas in the direction of SN 1993J in M81
    During the first few nights following its discovery, we observed the interstellar Ca II and Na I lines towards supernova 1993J at high spectral resolution (full width half maximum (FWHM) approximately 5-6 km/s) with the William Herschel Telescope at La Palma. We find a crowd of absorption components in the radial-velocity range -135 km/s less than

  • High-Speed Ultraviolet Monitoring in NGC 4151
    The rapidly variable Seyfert 1 galaxy NGC 4151 will be the subject of an intensive monitoring campaign with IUE, Rosat, GRO, ASCA and ground-based telescopes in December 1993. We will report preliminary results of 9.3 days of continuous monitoring with IUE, at a sampling rate of once every ~ 80 min, an order of magnitude faster than that achieved
