    The long bar as seen by the VVV Survey. II. Star counts
    Context. There is still some debate about the presence and the morphological properties of the long bar in the inner Galaxy. Aims: We investigate the...

    The long Galactic bar as seen by UKIDSS Galactic plane survey
    Context: Over the past decade there have been a series of results supporting the hypothesis of the existence of a long thin bar in the Milky Way with a half...

    The Magellanic Inter-Cloud Project (MAGIC) III: first spectroscopic evidence of a dwarf stripping a dwarf
    The Magellanic Bridge (MB) is a gaseous stream that links the Large (LMC) and Small (SMC) Magellanic Clouds. Current simulations suggest that the MB forms from...

    The MAGellanic Inter-Cloud Project (MAGIC). I. Evidence for Intermediate-age Stellar Populations in between the Magellanic Clouds
    The origin of the gas in between the Magellanic Clouds (MCs)—known as the "Magellanic Bridge" (MB)—is puzzling. Numerical simulations suggest that the MB formed...

    The Magellanic System: the puzzle of the leading gas stream
    The Magellanic Clouds (MCs) are the most massive gas-bearing systems falling into the Galaxy at the present epoch. They show clear signs of interaction...

    The magnitude difference between the main sequence turn off and the red giant branch bump in Galactic globular clusters
    We present new measurements of the magnitude of the main sequence turn off and the red giant branch bump in the luminosity function of a sample of Galactic...

    The mass of our Galaxy from satellite proper motions in the Gaia era
    We use Gaia DR2 systemic proper motions of 45 satellite galaxies to constrain the mass of the Milky Way using the scale-free mass estimator of Watkins et al....
  • Publication
    The messy death of a multiple star system and the resulting planetary nebula as observed by JWST
    Planetary nebulae—the ejected envelopes of red giant stars—provide us with a history of the last, mass-losing phases of 90% of stars initially more massive than...

    The metal-poor edge of the Milky Way's "thin disc"
    Context. The emergence of the disc in our Galaxy and the relation between thick and thin disc formation and evolution is still a matter of debate. The chemo...
