    The Pristine Survey - VIII. The metallicity distribution function of the Milky Way halo down to the extremely metal-poor regime
    The Pristine survey uses narrow-band photometry to derive precise metallicities down to the extremely metal-poor regime ( [Fe/H] < -3), and currently consists...

    The Pristine survey - XV. A CFHT ESPaDOnS view on the Milky Way halo and disc populations
    We present a one-dimensional, local thermodynamic equilibrium homogeneous analysis of 132 stars observed at high resolution with ESPaDOnS. This represents 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 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...

    The properties and evolution of a K-band selected sample of massive galaxies at z ~ 0.4-2 in the Palomar/DEEP2 survey
    We present the results of a study on the properties and evolution of massive (M* > 1011Msolar) galaxies at z ~ 0.4-2 utilizing Keck spectroscopy, near-infrared...

    The properties of galaxies in voids
    We present a comparison of the properties of galaxies in the most underdense regions of the Universe, where the galaxy number density is less than 10 per cent...

    The Properties of Quasar Hosts at the Peak of the Quasar Activity
    We present near-infrared imaging obtained with ESO VLT/ISAAC of a sample of 16 low luminosity radio-quiet quasars (RQQs) at the epoch around the peak of the...
