    The Pristine survey XI: the FORS2 sample
    Extremely metal-poor (EMP) stars are old objects that mostly formed very early after the big bang. They are rare and, to select them, we have to rely on low...

    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 Pristine survey: XXIII. Data Release 1 and an all-sky metallicity catalogue based on Gaia DR3 BP/RP spectro-photometry
    We used the spectro-photometric information of ∼219 million stars from Gaia's Data Release 3 (DR3) to calculate synthetic, narrowband, metallicity-sensitive...

    The Pristine survey: XXIV. The Galactic underdogs: Dynamic tales of a Milky Way metal-poor population
    Context. Metal-poor stars hold key information on the early Milky Way. Through the identification and characterisation of substructures, one can understand...

    The Pristine survey: XXV. The very metal-poor Galaxy: Chemodynamics through the follow-up of the Pristine-Gaia synthetic catalogue
    Context. The Pristine-Gaia synthetic catalogue of reliable photometric metallicities makes use of spectrophotometric information from Gaia DR3 XP spectra to...

    The Pristine survey: XXVI. Chemical abundances of subgiant stars of the extremely metal-poor stream C-19
    Context. The C-19 stellar stream is the most metal-poor stream known to date. While its wth and velocity dispersion indicate a dwarf galaxy origin, its...

    The prompt emission and peculiar break of GRB 060124
    Our multi-wavelength analysis of GRB 060124 shows the unusual behaviour of the decaying lightcurve as well as supporting the recently proposed phenomenon of...

    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...
