    The nuclear spectrum of M 87

    The nuclear spectrum of M 87 covering the Lyα-Hα wavelength range was obtained with the HST Faint Object Spectrograph (FOS) trough a 0″.21 aperture. Contrary to some previous claims, a single power law (F ...

    Morphology of the nuclear disk in M 87

    A deep, fully sampled diffraction limited (FWHM ∼ 70 mas) narrowband image of the central region in M 87 was obtained with the Wide Filed and Planetary Camera 2 of the Hubble Space Telescope using the dithering t...

    Imaging and Spectroscopy of Magellanic Cloud Planetary Nebulae obtained with the Hubble Space Telescope

    The majority of planetary nebulae (PNe) at the distance of the Magellanic Clouds typically subtend 1 arcsec or less on the sky. The Planetary Camera onboard the Hubble Space Telescope has a scale of 0.044 arcs...

    Hubble Space Telescope Observations of Planetary Nebulae in the Magellanic Clouds

    We present the results of our major HST study of the evolution of PN in the Magellanic Clouds. This consists of imaging studies in [O III] and FOS UV spectroscopy. These data are then used in theoretical photo...

    Planetary Nebulae and Halo Dynamics in Early Type Galaxies

    The study of extragalactic planetary nebulae has made rapid progress in recent years with the help of high quantum efficiency detectors. A brief but distinctive phase in the late stage of stellar evolution, pl...

    Imaging of Magellanic Cloud Planetary Nebulae with the Hubble Space Telescope

    We have obtained Hubble Space Telescope (HST) Planetary Camera (PC) images of a number of Magellanic Cloud planetary nebulae. The objects, except for SMP 83 were observed as part of the Cycle I GO program. The...

    Human placental cytotrophoblast cells: identification and culture

    Methods of disaggregation of human placental tissue were assessed with the aim of maximising the yield of cytotrophoblast cells and minimising contamination with other cell types. Brief exposure to crude tryps...

    Planetary Nebulae in Galaxies Beyond the Local Group

    Planetary nebulae can be used to estimate the distances to galaxies and to measure stellar dynamics in faint halos. We discuss surveys which have netted a total of 665 candidate planetary nebulae in NGC 5128 (...

    The effect of substrate and epidermal growth factor on human placental trophoblast cells in culture

    Attempts were made to select for trophoblast cells in cultures of mixed cell populations derived from preterm (7 to 12 wk) or term human placentas. Epidermal growth factor added to cultures on solid or porous ...

    Dynamics of Some Remote Superclusters

    Redshifts of clusters of galaxies have been obtained in four regions of the sky selected as suspected rich superclusters at intermediate redshift (0.1 < z < 0.3). Measurements to date have detected the existen...

    Thermal emission of Saturn's rings and disk at 34 µm

    OBSERVATIONS from aircraft of Saturn's thermal emission do not resolve the flux component of the rings from that of the planet1,2. Ground-based observations in the windows at 11 and 20 µm, which resolve the rings...
