Boxy/Peanut bulges, vertical buckling and galactic bars
I. Martinez-Valpuesta, E. Athanassoula
Boxy/peanut bulges in disk galaxies have been associated to stellar bars. In this talk, we discuss the different properties of such bulges and their relation with the corresponding…
Formation and evolution of bulges
E. Athanassoula, I. Martinez-Valpuesta
After presenting three ways of defining a bulge component in disc galaxies, we introduce the various types of bulges, namely the classical bulges, the boxy/peanut bulges and the di…
Studying the global dynamics of conservative dynamical systems using the SALI chaos detection method
T. Manos, Ch. Skokos, E. Athanassoula +1
We use the Smaller ALignment Index (SALI) method of chaos detection, to study the global dynamics of conservative dynamical systems described by differential or difference equation…
A bar in the inner halo of barred galaxies I. Structure and kinematics of a representative model
E. Athanassoula
N-body simulations argue that the inner haloes of barred galaxies should not be spherical, nor even axisymmetric, but triaxial. The departure from sphericity is strongest near the…
