Chemo-dynamics of the stellar component of the Sculptor dwarf galaxy II: dynamical properties and dark matter halo density
José María Arroyo Polonio, Raffaele Pascale, Giuseppina Battaglia +4
Dwarf galaxies satellite of the Milky Way are excellent laboratories for testing dark matter (DM) models and baryonic feedback implementation in simulations. The Sculptor 'classica…
The Pristine Dwarf-Galaxy survey -- VI. A VLT/FLAMES spectroscopic study of the dwarf galaxy Boötes II
Nicolas Longeard, Pascale Jablonka, Giuseppina Battaglia +4
The Milky Way has a large population of dwarf galaxy satellites. Their properties are sensitive to both cosmology and the physical processes underlying galaxy formation, but these…
How well can we unravel the accreted constituents of the Milky Way stellar halo? A test on cosmological hydrodynamical simulations
Guillaume F. Thomas, Giuseppina Battaglia, Robert J. J. Grand +1
Context. One of the primary goals of Galactic Archaeology is to reconstruct the Milky Way's accretion history. To achieve this, significant efforts have been dedicated to identifyi…
A 3D view of dwarf galaxies with Gaia and VLT/FLAMES II. The Sextans dwarf spheroidal
Eline Tolstoy, Giuseppina Battaglia, José María Arroyo-Polonio +7
The Sextans dwarf spheroidal galaxy has been challenging to study in a comprehensive way as it is highly extended on the sky, with an uncertain but large tidal radius of between 80…
Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal) II. Unveiling the formation and evolution of the kinematically selected Thick and Thin Discs
Emma Fernández-Alvar, Tomás Ruiz-Lara, Carme Gallart +16
Understanding the formation and evolution of the Milky Way's thin and thick discs is crucial to galaxy formation studies. We derive age and metallicity distributions of the kinemat…
