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…
Tidal origin of spiral arms in galaxies orbiting a cluster
Marcin Semczuk, Ewa L. Lokas, Andres del Pino
One of the scenarios for the formation of grand-design spiral arms in disky galaxies involves their interactions with a satellite or another galaxy. Here we consider another possib…
The Carina Project. X. On the kinematics of old and intermediate-age stellar populations
M. Fabrizio, G. Bono, M. Nonino +14
We present new radial velocity (RV) measurements of old (horizontal branch) and intermediate-age (red clump) stellar tracers in the Carina dwarf spheroidal. They are based on more…
Damping of the Milky Way bar by manifold-driven spirals
Ewa L. Lokas
We describe a new phenomenon of `bar damping' that may have played an important role in shaping the Milky Way bar and bulge as well as its spiral structure. We use a collisionless…
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…
The orbital structure of a tidally induced bar
Grzegorz Gajda, Ewa L. Lokas, E. Athanassoula
Orbits are the key building blocks of any density distribution and their study helps us understand the kinematical structure and the evolution of galaxies. Here we investigate orbi…
