    Evidence for temporal evolution in the M33 disc as traced by its star clusters
    We present precision radial velocities and stellar population parameters for 77 star clusters in the Local Group galaxy M33. Our Gran Telescopio de Canarias and...

    Exploring the local universe with massive stars
    Massive stars dominate the light output of entire galaxies, with luminosities in excess of 10 5 L⊙. This makes them powerful probes with which to study a range...

    Exploring the Very Extended Low-surface-brightness Stellar Populations of the Large Magellanic Cloud with SMASH
    We present the detection of very extended stellar populations around the Large Magellanic Cloud (LMC) out to R ∼ 21°, or ∼18.5 kpc at the LMC distance of 50 kpc...

    First Ground-based Charge-coupled Device Proper Motions for Fornax. II. Final Results
    We present the first entirely ground-based astrometric determination of the proper motion for the Fornax Local Group dwarf spheroidal satellite galaxy 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 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...

    Galactic Palaeontology
    I will talk about how resolved stellar populations in the nearby Local Group dwarf galaxies have been used to study the detailed chemical, kinematic and star...

    Giant HVC's and the Rotation Curves of the Milky Way and M31
    We have modelled, for the cases of Milky Way and M31, the effects on the galactic discs, of the arrival at high velocity (≥150 km s-1) of giant HI clouds, with...
