Dark matter distribution and dynamics of dwarf spheroidal galaxies
Ewa L. Lokas
I review the current status of dynamical modelling of dwarf spheroidal galaxies focusing on estimates of their dark matter content. Starting with the simplest methods using the vel…

Anatomy of a buckling galactic bar
Ewa L. Lokas
Using -body simulations we study the buckling instability in a galactic bar forming in a Milky Way-like galaxy. The galaxy is initially composed of an axisymmetric, exponential…

Buckling instability in tidally induced galactic bars
Ewa L. Lokas
Strong galactic bars produced in simulations tend to undergo a period of buckling instability that weakens and thickens them and forms a boxy/peanut structure in their central part…
