    Internal rotation of Milky Way dwarf spheroidal satellites with Gaia Early Data Release 3
    We present an analysis of the kinematics of 14 satellites of the Milky Way (MW). We use proper motions (PMs) from the Gaia Early Data Release 3 (EDR3) and line...

    Isolated galaxies in the Local Group .
    Dwarf galaxies in the Local Group allow to study in great detail the physical mechanisms responsible for the formation and evolution of galaxies. In fact, their...

    Kinematic and metallicity properties of the Aquarius dwarf galaxy from FORS2 MXU spectroscopy⋆
    Context. Dwarf galaxies found in isolation in the Local Group (LG) are unlikely to have interacted with the large LG spirals, and therefore environmental...

    Kinematic study of planetary nebulae in NGC 6822
    Context. The kinematics of planetary nebulae in external galaxies and in our own is a clue for understanding the behavior of the low- and intermediate-mass...

    Kinematics of the Local Group gas and galaxies in the HESTIA simulations
    We investigate the kinematic properties of gas and galaxies in the Local Group (LG) using high-resolution simulations performed by the HESTIA (High-resolution...

    Looking for the traces of the early Universe in the Fornax dSph galaxy
    We present the full Star Formation History as a function of radius of the Fornax dSph galaxy. We also present the preliminary results of the spatial...

    Luminous Blue Variables in the local universe
    Preliminary results of a candidate luminous blue variable (LBV) search made in a region of M33 are presented. The objects were found with narrow band filter...

    Luminous Red Stars in Local Group Dwarf Elliptical Galaxies: an Intermediate-Age Population?
    In this Letter, we show that the optically bright stars above the tip of the first red giant branch (TRGB) in the color-magnitude diagrams (CMDs) of nearby...

    Mass-metallicity relation of dwarf galaxies and its dependency on time: clues from resolved systems and comparison with massive galaxies
    Aims: We present a new approach to study the mass-metallicity relation and its dependency on time. Methods: We used the star formation history (SFH) derived...
