    A Candidate Massive Black Hole in the Low-metallicity Dwarf Galaxy Pair Mrk 709
    The incidence and properties of present-day dwarf galaxies hosting massive black holes (BHs) can provide important constraints on the origin of high-redshift BH...

    A Canis Major Overdensity Imaging Survey. I. Stellar Content and Star-Count Maps: A Distinctly Elongated Body of Main-Sequence Stars
    We present the first results from a large-area (~80deg×20deg), sparsely sampled, two-filter (B and R) imaging survey toward the Canis Major stellar overdensity...

    A catalog of warps in spiral and lenticular galaxies in the Southern hemisphere
    A catalog of optical warps of galaxies is presented. This can be considered complementary to that reported by Sánchez-Saavedra et al. (cite{sanchez-saavedra})...

    A catalogue of dwarf galaxy candidates around interacting galaxies
    We present results from the imaging of a sample of 12 interacting galaxies for which we have cataloged all potential dwarf systems in the vicinity of these...
