    An extreme ultra-diffuse galaxy with the mass of the Small Magellanic Cloud
    Extremely faint galaxies (mu_V>27 mag/arcsec^2), have only been discovered in the Local Group. These galaxies are very low in mass (tens of 10^5 Msun) and...

    An Extremly Oxygen-Poor Planetary Nebula In The Galactic Halo
    We report results of a spectrophotometric study of SBS 1150+599A, and discus s the nature of this object basing on our data. Our study shows that SBS 1150+599A...

    An H I view of the on-going assembly of early-type galaxies: present and future observations
    We present a preliminary analysis of the HI properties of early-type galaxies in the ATLAS3D sample. Using WSRT data for ~100 galaxies outside the Virgo cluster...

    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 Image of the Dust Sublimation Region in the Nucleus of NGC 1068
    The superb resolution of the Very Large Telescope Interferometer (VLTI) and the unrivalled sensitivity of GRAVITY have allowed us to reconstruct the first...

    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)...
