Chemo-dynamics of the stellar component of the Sculptor dwarf galaxy II: dynamical properties and dark matter halo density
José MarÃa 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…
A 3D view of dwarf galaxies with Gaia and VLT/FLAMES II. The Sextans dwarf spheroidal
Eline Tolstoy, Giuseppina Battaglia, José MarÃa 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…
Chemo-dynamics of the stellar component of the Sculptor dwarf galaxy I: observed properties
José MarÃa Arroyo-Polonio, Giuseppina Battaglia, Guillaume F. Thomas +3
Aims. Recently, both the presence of multiple stellar chemo-kinematic components and rotation in the Sculptor dwarf spheroidal galaxy have been put into question. Therefore, we re-…
The density of the Milky Way's corona at through ram pressure stripping of the Draco dSph galaxy
Asger Grønnow, Filippo Fraternali, Federico Marinacci +4
Satellite galaxies within the Milky Way's (MW) virial radius are typically devoid of cold gas due to ram pressure stripping by the MW's corona. The density of th…
