The Graininess of Dark Matter Haloes
Marcel Zemp, Jürg Diemand, Michael Kuhlen +5
We use the recently completed one billion particle Via Lactea II LambdaCDM simulation to investigate local properties like density, mean velocity, velocity dispersion, anisotropy,…
Large scale galactic turbulence: can self-gravity drive the observed HI velocity dispersions?
Oscar Agertz, George Lake, Romain Teyssier +3
Observations of turbulent velocity dispersions in the HI component of galactic disks show a characteristic floor in galaxies with low star formation rates and within individual gal…
Are ring galaxies the ancestors of giant low surface brightness galaxies?
M. Mapelli, B. Moore, E. Ripamonti +4
Giant low surface brightness galaxies (GLSBs) have flat discs extending up to ~100 kpc. Their formation is a puzzle for cosmological simulations in the cold dark matter scenario. W…
The origin of lopsidedness in galaxies
M. Mapelli, B. Moore, J. Bland-Hawthorn
It has long been known that a large fraction of disc galaxies are lopsided. We simulate three different mechanisms that can induce lopsidedness: flyby interactions, gas accretion f…
Formation and accretion history of terrestrial planets from runaway growth through to late time: implications for orbital eccentricity
Ryuji Morishima, Max W. Schmidt, Joachim Stadel +1
Remnant planetesimals might have played an important role in reducing the orbital eccentricities of the terrestrial planets after their formation via giant impacts. However, the po…
Lopsided galaxies: the case of NGC 891
M. Mapelli, B. Moore, J. Bland-Hawthorn
It has been known for a long time that a large fraction of disc galaxies are lopsided. We simulate three different mechanisms that can induce lopsidedness: flyby interactions, gas…
