    On the Central Helium-burning Variable Stars of the LeoI Dwarf Spheroidal Galaxy
    We present a study of short-period, central helium-burning variable stars in the Local Group dwarf spheroidal galaxy LeoI, including 106 RR Lyrae stars and 51...

    On the colors of barlenses and their link to B/P bulges
    Barlenses are morphological features present in barred galaxies with morphological types between S0 and Sb. Recently, they have been suggested to be the more...

    On the Compact H II Galaxy UM 408 as Seen by GMOS-IFU: Physical Conditions
    We present Integral Field Unit GMOS-IFU data of the compact H II galaxy UM 408, obtained at the Gemini South telescope, in order to derive the spatial...
  • Publication
    On the Connection Between Shape and Stellar Population in Early-type Galaxies
    We report on the discovery of a relation between the stellar mass M* of early-type galaxies (hereafter ETGs), their shape, as parameterized by the Sersic index...
  • Publication
    On the Connection of the Apparent Proper Motion and the VLBI Structure of Compact Radio Sources
    Many of the compact extragalactic radio sources that are used as fiducial points to define the celestial reference frame are known to have proper motions...
  • Publication
    On the Curvature of Dust Lanes in Galactic Bars
    We test the theoretical prediction that the straightest dust lanes in bars are found in strongly barred galaxies, or more specifically, that the degree of...
  • Publication
    On the dearth of C-enhanced metal-poor stars in the galactic bulge
    The chemical fingerprints of the first stars are retained within the photospheres of ancient unevolved metal-poor stars. A significant fraction of these stellar...

    On the Dearth of Ultra-faint Extremely Metal-poor Galaxies
    Local extremely metal-poor galaxies (XMPs) are of particular astrophysical interest since they allow us to look into physical processes characteristic of the...
