  • Publicación
    Gaia colour-magnitude diagrams of young open clusters. Identification in the UBC catalogue and comparison between manual and automated analyses
    Context. Automated analyses of Gaia astrometric data have led to the discovery of many new high-quality open cluster candidates. When a good determination of...

    Gaia DR 2 and VLT/FLAMES search for new satellites of the LMC
    A wealth of tiny galactic systems populates the surroundings of the Milky Way. However, some of these objects might have originated as former satellites of the...

    Gaia DR2 proper motions of dwarf galaxies within 420 kpc. Orbits, Milky Way mass, tidal influences, planar alignments, and group infall
    A proper understanding of the Milky Way (MW) dwarf galaxies in a cosmological context requires knowledge of their 3D velocities and orbits. However, proper...

    Gaia DR2 reveals a very massive runaway star ejected from R136
    A previous spectroscopic study identified the very massive O2 III star VFTS 16 in the Tarantula Nebula as a runaway star based on its peculiar line-of-sight...
  • Publicación
    Gaia early DR3 systemic motions of Local Group dwarf galaxies and orbital properties with a massive Large Magellanic Cloud
    Aims: We perform a comprehensive determination of the systemic proper motions of 74 dwarf galaxies and dwarf galaxy candidates in the Local Group based on Gaia...

    Gaia-DR2 extended kinematical maps . I. Method and application
    Context. The Gaia Collaboration has used Gaia-DR2 sources with six-dimensional (6D) phase space information to derive kinematical maps within 5 kpc of the Sun...

    Gaia-DR2 extended kinematical maps. II. Dynamics in the Galactic disk explaining radial and vertical velocities
    Context. In our Paper I, by using statistical deconvolution methods, extended kinematics maps of Gaia-DR2 data have been produced in a range of heliocentric...
  • Publicación
    Gaia-DR2 extended kinematical maps. III. Rotation curves analysis, dark matter, and MOND tests
    Context. Recent statistical deconvolution methods have produced extended kinematical maps in a range of heliocentric distances that are a factor of two to three...

    Gaia-ESO survey: Lithium abundances in open cluster Red Clump stars
    Context. It has recently been suggested that all giant stars with masses below 2 M ⊙ suffer an episode of surface lithium enrichment between the tip of the red...
