The major merger origin of the Andromeda II kinematics
Ivana Ebrová, Ewa L. Łokas, Sylvain Fouquet +1
Prolate rotation (i.e. rotation around the long axis) has been reported for two Local Group dwarf galaxies: Andromeda II, a dwarf spheroidal satellite of M31, and Phoenix, a transi…
The structure of Andromeda II dwarf spheroidal galaxy
Andrés del Pino, Ewa L. Lokas, Sebastian L. Hidalgo +1
We analyze in detail the spatial distribution and kinematic properties of two different stellar populations in Andromeda II (And II) dwarf spheroidal galaxy. We obtained their deta…
Formation of Andromeda II via a gas-rich major merger and an interaction with M31
Sylvain Fouquet, Ewa L. Lokas, Andres del Pino +1
Andromeda II (And II) has been known for a few decades but only recently observations have unveiled new properties of this dwarf spheroidal galaxy. The presence of two stellar popu…
Tidally induced bars of galaxies in clusters
Ewa L. Lokas, Ivana Ebrova, Andres del Pino +5
Using N-body simulations we study the formation and evolution of tidally induced bars in disky galaxies in clusters. Our progenitor is a massive, late-type galaxy similar to the Mi…
Co-orbiting satellite galaxy structures are still in conflict with the distribution of primordial dwarf galaxies
Marcel S. Pawlowski, Benoit Famaey, Helmut Jerjen +11
Both major galaxies in the Local Group host planar distributions of co-orbiting satellite galaxies, the Vast Polar Structure (VPOS) of the Milky Way and the Great Plane of Andromed…
Does the dwarf galaxy system of the Milky Way originate from Andromeda?
Sylvain Fouquet, François Hammer, Yanbin Yang +2
The Local Group is often seen to be a quiescent environment without significant merger events. However an ancient major merger may have occurred in the most massive galaxy. Numeric…
Does M31 result from an ancient major merger?
F. Hammer, Y. B. Yang, J. L. Wang +3
The numerous streams in the M31 halo are currently assumed to be due to multiple minor mergers. Here we use the GADGET2 simulation code to test whether M31 could have experienced a…
