Reconstructing the whole 6D properties of the Sagittarius stream with N-body simulations
Hai-Feng Wang, Yan-Bin Yang, Francois Hammer +1
It is a challenge to reproduce the full 6D space-phase properties of Sagittarius (Sgr) dwarf galaxy and its Stream simultaneously. Using N-body simulations with a Milky Way mass of…
Young stars discovered in dwarf spheroidal galaxies confirm their recent infall into the Milky way
Francois Hammer, Piercarlo Bonifacio, Elisabetta Caffau +10
Recent observations from the ESA Gaia satellite and with the ESO VLT, have identified the presence of a population of young, 0.5 to 2 Gyr old, stars in the halo and in dwarf sphero…
An intriguing coincidence between the majority of vast polar structure dwarfs and a recent major merger at the M31 position
Istiak Akib, François Hammer, Yanbin Yang +2
A significant part of the Milky Way (MW) dwarf galaxies orbit within a Vast POlar Structure (VPOS), which is perpendicular to the Galactic disc and whose origin has not yet been id…
The accretion history of the Milky Way IV. Hints of recent star formation in Milky Way dwarf spheroidal galaxies
Yanbin Yang, Elisabetta Caffau, Piercarlo Bonifacio +3
Dwarf spheroidal galaxies are known to be dominated by old stellar populations. This has led to the assumption that their gas-rich progenitors lost their gas during their infall in…
