Detecting chaotic and ordered motion in barred galaxies
T. Manos, E. Athanassoula
A very important issue in the area of galactic dynamics is the detection of chaotic and ordered motion inside galaxies. In order to achieve this target, we use the Smaller ALignmen…
Chaos and the dynamical evolution of barred galaxies
T. Manos, E. Athanassoula
The dynamical evolution of barred galaxies depends crucially on the fraction and their spacial distribution of chaotic orbits in them. In order to distinguish between the two kinds…
Formation and dynamical evolution of galaxies and of their components
E. Athanassoula
From this vast subject, I will pick out and review three specific topics, namely the formation and evolution of bars, the formation of bulges, and the evolution during multiple maj…
Interaction between a galactic disk and a live dark halo with an anisotropic velocity distribution
B. Fuchs, E. Athanassoula
We have extended previous analytical studies of the interaction of dark halos with galactic disks by introducing for the halo particles anisotropic distribution functions in phase…
Three-Dimensional Bar Structure and Disc/Bulge Secular Evolution
M. Bureau, G. Aronica, E. Athanassoula
Kn-band imaging of a sample of 30 edge-on spiral galaxies with a boxy or peanut-shaped (B/PS) bulge is discussed. Galaxies with a B/PS bulge tend to have a more complex morphology…
Can bars be destroyed by a central mass concentration? I. Simulations
E. Athanassoula, J. C. Lambert, W. Dehnen
We study the effect of a central mass concentration (CMC) on the secular evolution of a barred disc galaxy. Unlike previous studies, we use fully self-consistent 3D -body simula…
