    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 carbon dwarf wearing a Necklace: first proof of accretion in a post-common-envelope binary central star of a planetary nebula with jets
    The formation of collimated outflows or jets in planetary nebulae (PNe) is not well understood. There is no evidence for active accretion discs in PNe, making...

    A Case against a Significant Detection of Precession in the Galactic Warp
    Recent studies of warp kinematics using Gaia DR2 data have produced detections of warp precession for the first time, which greatly exceeds theoretical...

    A case against an X-shaped structure in the Milky Way young bulge
    Context. A number of recent papers have claimed the discovery of an X-shape structure in the bulge of our Galaxy in the population of the red clumps. Aims: We...

    A case study of hurdle and generalized additive models in astronomy: the escape of ionizing radiation
    The dark ages of the Universe end with the formation of the first generation of stars residing in primeval galaxies. These objects were the first to produce...
  • Publication
    A Catalog of li Abundances and Equivalent Widths in a Sample of Galactic C-Stars
    In the first two papers of this series, we derived and discussed the abundances of lithium in a sample of 161 galactic carbon stars. Here, we extend this sample...
  • Publication
    A catalog of observed nuclear magnitudes of Jupiter family comets
    A catalog of a sample of 105 Jupiter family (JF) comets (defined as those with Tisserand constants T > 2 and orbital periods P 20 yr) is presented with our `...
  • Publication
    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})...
  • Publication
    A Catalogue and analysis of ultra-diffuse galaxy spectroscopic properties
    In order to facilitate the future study of ultra-diffuse galaxies (UDGs), we compile a catalogue of their spectroscopic properties. Using it, we investigate...
