  • Barred galaxies

N-body simulation of barred galaxy

Face-on This simulation shows the evolution of a barred spiral galaxy. Only stars are shown, and colors represent their density. The dark matter halo is also present in the calculations, but not displayed in this animation.

N-body simulation of barred galaxy (almost edge-on)

Edge-on (almost) When the same galaxy is viewed under an inclination angle, one may notice the vertical thickness of the peanut-shaped bulge.

N-body simulation of barred galaxy (disk and halo)

Stellar disk and dark matter halo In this animation we see the evolution of a barred galaxy (in blue), but also of its dark matter halo (in orange). Both are seen face-on and edge-on. As the bar develops, the initially flattened halo becomes more spherical. For details, see the paper Machado & Athanassoula (2010).

N-body simulation of barred galaxy (slow)

Slowly rotating This animation shows the stellar disk of a simulated barred galaxy. Displaying more frequent time steps provides a better glimpse of the orbital structure.
