Most dwarf spheroidal galaxies surrounding the Milky Way cannot be dark-matter dominated satellites
Francois Hammer, Yanbin Yang, Frederic Arenou +5
Milky Way dwarf spheroidal galaxies are the tiniest observed galaxies and are currently associated with the largest fractions of dark matter, which is revealed by their too large v…
A Recent Major Merger Tale for the Closest Giant Elliptical Galaxy Centaurus A
Jianling Wang, Francois Hammer, Marina Rejkuba +2
We have used hydrodynamical simulations to model the formation of the closest giant elliptical galaxy, Centaurus A. We find that a single major merger event with a mass ratio up to…
Orbital evidences for dark-matter-free Milky Way dwarf spheroidal galaxies
Francois Hammer, Yanbin Yang, Frederic Arenou +4
The nature of Milky Way dwarf spheroidals (MW dSphs) has been questioned, in particular whether they are dominated by dark matter (DM). Here we investigate an alternative scenario,…
