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…
HST Proper Motion of Andromeda III: Another Satellite Co-orbiting The M31 Satellite Plane
Dana I. Casetti-Dinescu, Marcel S. Pawlowski, Terrence M. Girard +5
We measure the absolute proper motion of Andromeda III using ACS/WFC and WFPC2 exposures spanning an unprecedented 22-year time baseline. The WFPC2 exposures have been processed us…
The Accretion History of the Milky Way: III. Hydrodynamical Simulations of Galactic Dwarf Galaxies at First Infall
Jianling Wang, Francois Hammer, Yanbin Yang +3
Most Milky Way dwarf galaxies are much less bound to their host than are relics of Gaia-Sausage-Enceladus and Sgr. These dwarfs are expected to have fallen into the Galactic halo l…
The accretion history of the Milky Way. II. Internal kinematics of globular clusters and of dwarf galaxies
Francois Hammer, Jianling Wang, Gary A. Mamon +7
We study how structural properties of globular clusters and dwarf galaxies are linked to their orbits in the Milky Way halo. From the inner to the outer halo, orbital energy increa…
3D hydrodynamic simulations for the formation of the Local Group satellite planes
Indranil Banik, Ingo Thies, Roy Truelove +5
The existence of mutually correlated thin and rotating planes of satellite galaxies around both the Milky Way (MW) and Andromeda (M31) calls for an explanation. Previous work in Mi…
An extended stellar halo discovered in the Fornax dwarf spheroidal using Gaia EDR3
Yanbin Yang, Francois Hammer, Yongjun Jiao +1
We have studied the extent of the Red Giant Branch stellar population in the Fornax dwarf spheroidal galaxy using the spatially extended and homogeneous data set from Gaia EDR3. Ou…
