Are ring galaxies the ancestors of giant low surface brightness galaxies?
M. Mapelli, B. Moore, E. Ripamonti +3
We simulate the collisional formation of a ring galaxy and we integrate its evolution up to 1.5 Gyr after the interaction. About 100-200 Myr after the collision, the simulated gala…
The Source of Ionization along the Magellanic Stream
J. Bland-Hawthorn, R. Sutherland, O. Agertz +1
Since its discovery in 1996, the source of the bright H-alpha emission (up to 750 mR) along the Magellanic Stream has remained a mystery. There is no evidence of ionising stars wit…
The formation of ultra-compact dwarf galaxies and nucleated dwarf galaxies
Tobias Goerdt, Ben Moore, Stelios Kazantzidis +3
Ultra compact dwarf galaxies (UCDs) have similar properties as massive globular clusters or the nuclei of nucleated galaxies. Recent observations suggesting a high dark matter cont…
Multimass spherical structure models for N-body simulations
Marcel Zemp, Ben Moore, Joachim Stadel +2
We present a simple and efficient method to set up spherical structure models for N-body simulations with a multimass technique. This technique reduces by a substantial factor the…
The Causes of Halo Shape Changes Induced by Cooling Baryons: Disks Versus Substructures
Victor P. Debattista, Ben Moore, Thomas Quinn +5
Cold dark matter cosmogony predicts triaxial dark matter halos, whereas observations find quite round halos. This is most likely due to the condensation of baryons leading to round…
Influence of Orbital Behaviour and Chaos on the Shape of Dark Matter Halos
Andrea V. Maccio', Ioannis Sideris, Marco Miranda +2
It has been shown that the dissipative gas infall during galaxy formation has the capability to modify the shape of dark matter halos. In this paper we perform the first detailed a…
