    The Pristine Inner Galaxy Survey (PIGS) VII: a discovery of the first inner Galaxy CEMP-r/s star
    Well-studied very metal-poor (VMP, [Fe/H] <-2) stars in the inner Galaxy are few in number, and they are of special interest because they are expected to be...

    The Pristine survey - XIX. Cu and Zn abundances in metal-poor giants
    Metal-poor stars formed from a gas enriched by the ejecta of the explosion of one/few generations of first massive stars. With the Pristine photometry combined...

    The Pristine survey - XVI. The metallicity of 26 stellar streams around the Milky Way detected with the STREAMFINDER in Gaia EDR3
    We use the photometric metallicities provided by the panoramic Pristine survey to study the veracity and derive the metallicities of the numerous stellar...

    The Pristine survey - XVII. The C-19 stream is dynamically hot and more extended than previously thought
    The C-19 stream is the most metal-poor stellar system ever discovered, with a mean metallicity [Fe/H] = -3.38 ± 0.06. Its low metallicity dispersion (σ [Fe/H] <...

    The Pristine survey - XVIII. C-19: tidal debris of a dark matter-dominated globular cluster?
    The recently discovered C-19 stellar stream is a collection of kinematically associated metal-poor stars in the halo of the Milky Way lacking an obvious...

    The Pristine survey XIII: uncovering the very metal-poor tail of the thin disc
    We evaluate the rotational velocity of stars observed by the Pristine survey towards the Galactic anticentre spanning a wide range of metallicities from the...

    The Proper Motion Field of the Small Magellanic Cloud: Kinematic Evidence for Its Tidal Disruption
    We present a new measurement of the systemic proper motion of the Small Magellanic Cloud (SMC), based on an expanded set of 30 fields containing background...

    The Proper Motion of the Magellanic Clouds. I. First Results and Description of the Program
    We present the first results of a ground-based program to determine the proper motion of the Magellanic Clouds (MCs) relative to background quasars (QSO), being...

    The Proper-motion Field along the Magellanic Bridge: A New Probe of the LMC–SMC Interaction
    We present the first detailed kinematic analysis of the proper motions (PMs) of stars in the Magellanic Bridge, from both the Gaia Data Release 2 catalog and...
