    An Iceberg Scenario for Late-Type Spiral Galaxy Bulges
    Fitting exponential profiles to the bulges of the early-type spiral galaxies from de Jong & van der Kruit (1994) under-estimates their sizes at the 2-3 sigma...

    An idealized model for dust accretion in active galactic nuclei
    With an adequate supply of matter, the inward drifting of dust particles induced by the Poynting-Robertson effect can lead to the formation of a shell or disk...

    An Imaging Survey of Nearby Spiral Galaxies
    We describe the progress of a large optical and near-infrared imaging study of a complete sample of 57 spiral galaxies. We have obtained B, I, K' and Hα imaging...
  • Publication
    An Imaging Survey of Satellite Galaxies
    We have made B, V, and I-band observations of satellite galaxies which lie around isolated disk galaxies, using the satellite sample of Zaritsky et al. (1997)...
