    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 Chemical Abundances of Miras in Clusters: V1 in the Metal-rich Globular NGC 5927
    We present the first spectroscopic abundance determination of iron, α-elements (Si, Ca, and Ti), and sodium for the Mira variable V1 in the metal-rich globular...

    On the Density Profile of the Globular Cluster M92
    We present new number density and surface brightness profiles for the globular cluster M92 (NGC 6341). These profiles are calculated from optical images...

    On the Distance and Reddening of the Starburst Galaxy IC 10
    We present deep and accurate optical photometry of the Local Group starburst galaxy IC 10. The photometry is based on two sets of images collected with the...

    On the dust content of galaxy clusters
    Context. Most of the contribution to dust emission in clusters of galaxies comes from late-type galaxies. However, several ejection processes of material from...

    On the Dwarf Irregular Galaxy NGC 6822. I. Young, Intermediate, and Old Stellar Populations
    We present accurate and deep multiband (g, r, i) photometry of the Local Group dwarf irregular galaxy NGC 6822. The images were collected with wide-field...

    On the early evolution of Local Group dwarf galaxy types: star formation and supernova feedback
    According to star formation histories (SFHs), Local Group dwarf galaxies can be broadly classified in two types: those forming most of their stars before z = 2...

    On the Extended Structure of the Phoenix Dwarf Galaxy
    We present the star formation history (SFH) and its variations with galactocentric distance for the Local Group dwarf galaxy of Phoenix. They have been derived...

    On the Kinematic Separation of Field and Cluster Stars across the Bulge Globular NGC 6528
    We present deep and precise multi-band photometry of the Galactic bulge globular cluster NGC 6528. The current data set includes optical and near-infrared...
