    The Pristine survey - XX. GTC follow-up observations of extremely metal-poor stars identified from Pristine and LAMOST
    Ultra-metal-poor stars ($\rm {[Fe/H]} \lt -4.0$) are very rare, and finding them is a challenging task. Both narrow-band photometry and low-resolution...

    The Pristine survey - XXII. A serendipitous discovery of an extremely Li-rich very metal-poor giant and a new method of <SUP>6</SUP>Li/<SUP>7</SUP>Li isotope measurement
    We report the serendipitous discovery of a very metal-poor (VMP) Li-rich giant star (T eff = 4690 ± 80 K, log g = 1.34 ± 0.13, [Fe/H] = -2.43 ± 0.07). We...

    The Pristine survey II: A sample of bright stars observed with FEROS
    Extremely metal-poor (EMP) stars are old objects formed in the first Gyr of the Universe. They are rare and, to select them, the most successful strategy has...

    The Pristine survey IV: approaching the Galactic metallicity floor with the discovery of an ultra-metal-poor star
    The early Universe presented a star formation environment that was almost devoid of heavy elements. The lowest metallicity stars thus provide a unique window...

    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 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...
