Rings, spirals and manifolds
E. Athanassoula, M. Romero-Gomez, J. J. Masdemont
Two-armed, grand design spirals and inner and outer rings in barred galaxies can be due to orbits guided by the manifolds emanating from the vicinity of the L1 and L2 Lagrangian po…
Boxy/peanut bulges : formation, evolution and properties
E. Athanassoula, I. Martinez-Valpuesta
We discuss the formation and evolution of boxy/peanut bulges (B/Ps) and present new simulations results. Orbital structure studies show that B/Ps are parts of bars seen edge-on, th…
Topics on bar and bulge formation and evolution
E. Athanassoula
I discuss results from the COSMOS survey, showing that the fraction of disc galaxies that is barred decreases considerably with look-back time from z ~ 0.2 to z ~ 0.8. This decreas…
Boxy/peanut and discy bulges : formation, evolution and properties
E. Athanassoula
The class `bulges' contains objects with very different formation and evolution paths and very different properties. I review two types of `bulges', the boxy/peanut bulges (B/Ps) a…
Dynamical study of 2D and 3D barred galaxy models
T. Manos, E. Athanassoula
We study the dynamics of 2D and 3D barred galaxy analytical models, focusing on the distinction between regular and chaotic orbits with the help of the Smaller ALigment Index (SALI…
Gamma ray and Neutrino fluxes from a cosmological dark matter simulation
E. Athanassoula, F. -S. Ling, E. Nezri +1
In this paper, we estimate the gamma-ray and neutrino fluxes coming from dark matter annihilation in a Milky Way framework provided by a recent N-BODY HORIZON simulation. We first…
