Preservation of Cuspy Profiles in Disk Galaxy Mergers
Hector Aceves, Hector Velazquez
We carried out three self-consistent -body simulations of galaxy mergers, with a cuspy dark matter profile, in order to study if the inner dark density slope is preserved in the…
N-Body Simulations of Small Galaxy Groups
Hector Aceves, Hector Velazquez
A series of N-body simulations aimed to study the dynamics of small groups of galaxies are presented. The properties of small galaxy groups are very well reproduced, and those of H…
Sinking Satellites and the Heating of Galaxy Discs
H. Velazquez, Simon D. M. White
We have carried out a set of self-consistent N-body simulations to study the interaction between disc galaxies and merging satellites with the aim of determining the disc kinematic…
On the Dynamics of the Sagittarius Dwarf Galaxy
H. Velazquez, S. D. M. White
We use numerical simulations to test the feasibility of the suggestion by Ibata et al. (1994) that the excess population of stars which they discovered in the Sagittarius region ma…
