    Distribution and Content of Dust in Overlap** Galaxy Systems

    We present a progress report on our program to determine the opacity of spiral disks directly, rather than statistically, by imaging foreground spirals partially projected against background galaxies. The non-ove...

    Stellar Populations in Mixed Pairs of Galaxies

    The interpration of the interaction in galaxies is simplified in mixed pairs (E+S) because most or all of the cold gas can be traced to an origin in a single galaxy (S). We used spectroscopy, imaging, far-IR, ...

    Nuclear Activity: How Irritating Are Neighbours?

    Many observational studies in the last decade have strongly suggested that galaxy - galaxy interactions do affect the properties of spiral galaxies, in particular the properties of their nuclei. The first indi...

    The Effects of Galaxy — Galaxy Interactions on Nuclear Activity

    The notion that galaxy — galaxy interactions do affect the properties of galaxy nuclei is not new. The earliest indications come from surveys of the radio continuum emission from spiral galaxies. Sulentic (197...
